Detach from the Interpreter for Long-Running Rust Work (Highest Impact) + +In PyO3 0.28, `Python::allow_threads` has been renamed to **`Python::detach`**. This is the single most important optimization — it allows the Python interpreter to proceed without waiting for the current thread. + +On **GIL-enabled builds**, this is crucial as only one thread may be attached at a time. On **free-threaded builds** (Python 3.13t/3.14t), this is still essential because "stop the world" events (like garbage collection) force all attached threads to wait. + +**Rule of thumb:** Attaching/detaching takes <1ms, so any work expected to take multiple milliseconds benefits from detaching. + +```rust +use pyo3::prelude::*; +use pyo3::types::PyBytes; + +#[pyfunction] +fn parse_response<'py>(py: Python<'py>, data: &[u8]) -> PyResult> { + // ✅ Detach from interpreter during pure-Rust work + let parsed = py.detach(|| { + serde_json::from_slice::(data) + }).map_err(|e| pyo3::exceptions::PyValueError::new_err(e.to_string()))?; + + // Re-attach automatically; convert to Python only here + pythonize::pythonize(py, &parsed) +} +``` + +**Batch pattern — minimize attached time:** + +```rust +use rayon::prelude::*; + +#[pyfunction] +fn process_batch<'py>(py: Python<'py>, items: Vec) -> PyResult> { + // Phase 1: Detach and do heavy Rust work in parallel + let results = py.detach(|| { + items.into_par_iter() + .map(|item| item.to_uppercase()) // example transform + .collect::>() + }); + + // Phase 2: Return — PyO3 handles Vec → list[str] conversion + Ok(results) +} +``` + +--- + +## 2. Use `cast` Instead of `extract` for Type Checks + +This comes directly from the [PyO3 0.28 performance guide](https://pyo3.rs/v0.28.0/performance.html).

Zero-Cost Python Token Access via `Bound::py()` + +Another tip from the official performance page: if you already have a `Bound<'py, T>` reference, use `.py()` to get the `Python<'py>` token instead of calling `Python::attach`. `Python::attach` has a small but measurable cost from checking if the thread is already attached. + +```rust +use pyo3::prelude::*; +use pyo3::types::PyList; + +struct Inner(Py); + +struct InnerBound<'py>(Bound<'py, PyList>); + +impl PartialEq for InnerBound<'_> { + fn eq(&self, other: &Inner) -> bool { + // ✅ Zero-cost token access from existing Bound reference + let py = self.0.py(); + let other_len = other.0.bind(py).len(); + self.0.len() == other_len + } +} + +// ❌ Avoid: unnecessary Python::attach when you already have a Bound +// Python::attach(|py| { ... }) // has overhead from attachment check +``` + +--- + +## 4. Use Vectorcall Protocol for Calling Python + +PyO3 0.28 will use the more efficient `vectorcall` protocol (PEP 590) when you pass **Rust tuples** as call arguments. `Bound<'_, PyTuple>` and `Py` can only use the older, slower `tp_call` protocol. + +```rust +use pyo3::prelude::*; + +#[pyfunction] +fn call_callback(py: Python<'_>, callback: &Bound<'_, PyAny>) -> PyResult { + // ✅ Rust tuple → vectorcall (fast path) + let result = callback.call1((42, "hello", true))?; + + // ❌ Avoid: PyTuple → tp_call (slower path) + // let args = PyTuple::new(py, &[42.into_pyobject(py)?, ...])?; + // let result = callback.call1(args)?; + + Ok(result.unbind()) +} +``` + +**Key rule:** Prefer Rust tuples `(arg1, arg2, ...)` over constructing `PyTuple` for all `.call()`, `.call1()`, and `.call_method1()` invocations. + +--- + +## 5. Disable the Global Reference Pool + +PyO3 maintains a global mutable reference pool for deferred reference count updates when `Py` is dropped without being attached to the interpreter. The synchronization overhead can become significant at the Python-Rust boundary. + +Add to your `.cargo/config.toml`: + +```toml +[build] +rustflags = ["--cfg", "pyo3_disable_reference_pool"] +``` + +**Tradeoff:** With this flag, dropping a `Py` (or types containing it like `PyErr`, `PyBackedStr`, `PyBackedBytes`) without being attached will **abort**. So you must ensure all Python objects are dropped while attached: + +```rust +use pyo3::prelude::*; +use pyo3::types::PyList; + +// ✅ Correct: drop within an attached context +let numbers: Py = Python::attach(|py| PyList::empty(py).unbind()); + +Python::attach(|py| { + numbers.bind(py).append(42).unwrap(); +}); + +// Explicitly drop while attached +Python::attach(move |py| { + drop(numbers); // Safe — we're attached +}); +``` + +Optionally add `pyo3_leak_on_drop_without_reference_pool` to leak instead of abort (prevents crashes but may cause resource exhaustion long-term). + +--- + +## 6.

When requests fell back to self._client.send() instead of using the transport, TLS certificate verification was still enabled. Changes: - Add verify parameter to Client::new_impl() and AsyncClient::new_impl() - Pass verify from Python Client/AsyncClient to Rust constructors - Use tls_danger_accept_invalid_certs() in Rust clients when verify=false - Update transport.rs to use non-deprecated tls_danger_accept_invalid_certs This fixes HTTPS requests to servers with self-signed certificates when using Client(verify=False) or AsyncClient(verify=False).

core**: HTTP operations handled by Rust's reqwest library +- **Efficient GIL management**: Releases Python GIL during I/O operations +- **Connection pooling**: Rust's hyper provides efficient

It provides two different configurations to suit various testing needs: a high-performance **Traefik Load Balancer** setup and a **Simple HTTPBin** setup. + +## 📋 Overview + +The server setup is designed to provide a consistent and controlled environment for performance testing. Using a local server eliminates network variability and allows for deep analysis of client library behavior under different conditions. + +- **Traefik Load Balancer Setup**: Simulates a production-like environment with a reverse proxy, SSL/TLS termination, and load balancing across multiple instances. +- **Simple HTTPBin Setup**: A lightweight, single-instance configuration for basic testing and debugging. + +--- + +## ⚡ Quick Start + +### Start Traefik Load Balancer (Recommended) +```bash +docker-compose -f httpbin_server/docker-compose.yml up -d +``` + +### Start Simple HTTPBin +```bash +docker-compose -f httpbin_server/docker-compose.simple.yml up -d +``` + +### Stop the Server +```bash +docker-compose -f httpbin_server/docker-compose.yml down +# OR +docker-compose -f httpbin_server/docker-compose.simple.yml down +``` + +--- + +## 🏗 Traefik Load Balancer Setup (Advanced) + +The advanced setup uses **Traefik v3** as a reverse proxy and load balancer. This is the recommended configuration for comprehensive benchmarking. + +### Features +- **Load Balancing**: Distributes incoming requests across 3 `httpbin` instances (`httpbin1`, `httpbin2`, `httpbin3`) using a round-robin algorithm. +- **HTTPS Support**: Provides both HTTP and HTTPS endpoints using self-signed certificates. +- **Automatic Discovery**: Traefik automatically discovers and routes traffic to the `httpbin` services. +- **Health Monitoring**: Includes health checks for both Traefik and the backend instances. +- **Resource Limits**: Each `httpbin` instance is limited to 1.0 CPU and 512MB RAM to ensure stable performance. + +### Endpoints +- **HTTP**: `http://localhost/` (Port 80) +- **HTTPS**: `https://localhost/` (Port 443) +- **Traefik Dashboard**: `http://localhost:8080` (For monitoring and debugging) + +### Testing the Setup +```bash +# Test HTTP endpoint +curl -I http://localhost/get + +# Test HTTPS endpoint (using -k to ignore self-signed certificate) +curl -k -I https://localhost/get +``` + +### Starting the Server +```bash +docker-compose -f httpbin_server/docker-compose.yml up -d +``` + +--- + +## 🧪 Simple HTTPBin Setup (Basic) + +The simple setup runs a single `httpbin` instance exposed directly on port 80. + +### When to use this setup: +- Basic connectivity tests. +- Debugging custom headers or request bodies. +- Low-resource environments where a full load balancer is not needed. + +### Endpoints +- **HTTP**: `http://localhost/` (Port 80) + +### Testing the Setup +```bash +curl -I http://localhost/get +``` + +### Starting the Server +```bash +docker-compose -f httpbin_server/docker-compose.simple.yml up -d +``` + +--- + +## ⚙️ Configuration Details + +### Traefik Static Configuration (`traefik_config.yml`) +Configures core entrypoints (80, 443), log levels, and the Docker/File providers. + +### Dynamic Routing Rules (`traefik/dynamic/httpbin-routing.yml`) +Defines how requests are routed to the load-balanced services. It matches requests with `Host: localhost` and maps them to the `httpbin` service consisting of three backend URLs. + +### TLS/SSL Setup +- **Config**: `traefik/dynamic/tls.yml` points to the certificates. +- **Certificates**: Located in `certs/server.crt` and `certs/server.key`. +- **Note**: These are self-signed certificates. You may need to disable SSL verification in your benchmark client or trust the certificate. + +### Load Balancing Behavior +Traefik uses a round-robin strategy by default. You can verify this by checking the `X-Forwarded-For` or other headers if the backend instances were configured to log their unique IDs, but in this setup, it's handled transparently by Traefik. + +--- + +## 🛠 Troubleshooting + +### Port Conflicts +If you see an error like `Bind for 0.0.0.0:80 failed: port is already allocated`, ensure no other web servers (like Nginx or Apache) are running on your host. +- Check ports: `lsof -i :80` or `netstat -tuln | grep :80` + +### Docker Socket Permissions +Traefik needs access to `/var/run/docker.sock` to discover services. If you encounter permission issues, ensure your user is in the `docker` group or run with appropriate permissions. + +### SSL Verification Errors +When testing HTTPS, you might see `CERTIFICATE_VERIFY_FAILED`. +- **Curl**: Use the `-k` or `--insecure` flag. +- **Benchmark Tool**: Ensure the client adapter handles self-signed certificates (most adapters in this project support an `--insecure` or similar flag if implemented). + +--- + +## 📈 Integration with Benchmark Framework + +This server setup is optimized for use with the `http-client-benchmarker` CLI. + +### Example: Benchmarking against the Load Balancer +```bash +# Benchmark httpx against the HTTP endpoint +python -m http_benchmark.cli --url http://localhost/get --client httpx --concurrency 50 --duration 60 + +# Benchmark aiohttp against the HTTPS endpoint +python -m http_benchmark.cli --url https://localhost/get --client aiohttp --concurrency 50 --duration 60 --async +``` + +### Recommended Setup for Performance Testing +For high-concurrency benchmarks, always use the Traefik setup. It better reflects real-world scenarios where requests are proxied and distributed across multiple worker nodes, allowing you to test how client libraries handle connection pooling and keep-alive over a load balancer. diff --git a/httpbin_server/certs/server.crt b/httpbin_server/certs/server.crt new file mode 100644 index 0000000..0675ded --- /dev/null +++ b/httpbin_server/certs/server.crt @@ -0,0 +1,19 @@ +-----BEGIN CERTIFICATE----- +MIIDCTCCAfGgAwIBAgIUGiDR48weKWpA5zhm8uwSQqncd+YwDQYJKoZIhvcNAQEL +BQAwFDESMBAGA1UEAwwJbG9jYWxob3N0MB4XDTI2MDExMDAxMDgzNFoXDTI3MDEx +MDAxMDgzNFowFDESMBAGA1UEAwwJbG9jYWxob3N0MIIBIjANBgkqhkiG9w0BAQEF +AAOCAQ8AMIIBCgKCAQEAqNeLgOOoh3pvWB2yydsoyUrvbWrjD70ehrcHNS/ilNOC +GNFcLwkTgbJFwQ90l6GepShkXjDwSfXE7BTtsP7V9ripTpT3sMiBG5q4LE9hoVVW +/MoWq81WM4MCZgOxQpZF6V5P2kEm9F2s7UF1V/nZqAFJHu4BWD8R76lngB3NRY3k ++mlpPzxXkLk3Bq+b88n3eUcStyA1o5/9x6H2YCESbrA/xPktu812nRSSGvK+dKH8 +MrAP5PtUL7azjEEtWA9JN/uc3q5EKSe3NeowfWi6sX5hPXG+9nhNF4VTal4Ev3Nz +RAYuEvAu3HZh0xAvZcr6ZmWuDOaS0DdnR/Hte25tswIDAQABo1MwUTAdBgNVHQ4E +FgQUzpmnlnmTjd+e1QSFILEa3/K5fIQwHwYDVR0jBBgwFoAUzpmnlnmTjd+e1QSF +ILEa3/K5fIQwDwYDVR0TAQH/BAUwAwEB/zANBgkqhkiG9w0BAQsFAAOCAQEAYGM5 +SZvDw2Bj1ee5ZvqGMsprtv0zv/hMQak8BNvAs1tpgHpChqogn9NEXUVaSMs5Sa1W +TCMv2oc1Ort1JQVZjOSiDPf5o9p/zqcO/n1vTph8ZY+T9pdvGkGzQ33KZqbge3hO +Hy7H5FuRDWJz+xThx2g9RDr4xvN6tyCIp+xboX40dWJHorHaqkOPgSF/NfuQdyEE +Hi16wfhGpPunVjKk+ZkkIYyK6n5eJqS/SEAGbPAgT9FMuonqtjhapam/ZYyVuy8J +B9vwbUA0lHD1ET1VxxQx2k9rDLGv7tV27uTMop4Q4cW6wEaho+nzGPSCh2yYn6Qz +VpwXmVlxt7yOjKCbzA== +-----END CERTIFICATE----- diff --git a/httpbin_server/certs/server.key b/httpbin_server/certs/server.key new file mode 100644 index 0000000..a769892 --- /dev/null +++ b/httpbin_server/certs/server.key @@ -0,0 +1,28 @@ +-----BEGIN PRIVATE KEY----- +MIIEvgIBADANBgkqhkiG9w0BAQEFAASCBKgwggSkAgEAAoIBAQCo14uA46iHem9Y +HbLJ2yjJSu9tauMPvR6Gtwc1L+KU04IY0VwvCROBskXBD3SXoZ6lKGReMPBJ9cTs +FO2w/tX2uKlOlPewyIEbmrgsT2GhVVb8yharzVYzgwJmA7FClkXpXk/aQSb0Xazt +QXVX+dmoAUke7gFYPxHvqWeAHc1FjeT6aWk/PFeQuTcGr5vzyfd5RxK3IDWjn/3H +ofZgIRJusD/E+S27zXadFJIa8r50ofwysA/k+1QvtrOMQS1YD0k3+5zerkQpJ7c1 +6jB9aLqxfmE9cb72eE0XhVNqXgS/c3NEBi4S8C7cdmHTEC9lyvpmZa4M5pLQN2dH +8e17bm2zAgMBAAECggEACeRC3IS56WH/ZvKqeE/6JjzZJRhngBMM2Eidx/xrsltn +2ktdsrW96lHG62Yb5wxFbpictLX6ReL7q/cX69AqOd+cr6ljj3xXsAXS92mZJyoI +RBwU0vDfNXpd6BscRfHm26K2W+uIPDXGvUmh9csB+OlGXuUDuCdNxjQvB573WTU7 +5TJXdcXPNo63YNsPJlKtOnZc3xwG7xJrQDJWj0ReZZDEwYDIPRU8sWqdrs++s1Nz +WhpGhEtgZSrsJYeYsxkvPm9d95gyIxbQeX1wDkZ3Kq5jHIHvFGBYsrJC435Ik7wE +DZRsLX9w3e8uQjhp1US4yyaO2d4BPbc1+nJvfV3QFQKBgQDqbneW7Vz9bl7PkyTf +3iwJKbMFegUr3X+/eDr0jvVXuXA1ROGlnGdnhQmeBfvP3dObyhEVKM8dEjg29DXv +foLo8rDkaOFDpMxjW6CVWpKYO29J8fk/O0JzGJbATehNQu84tUp8o+fE/4h9QuRQ +5ixsbf2q127gLFr14S2VbmKaRQKBgQC4YEGno9TzoTUrknM7NXdKA3Zb4lV56k6g +v6T2+a5NVNwj0aIiN+dKbLu0AwAZW0nQa3I7eN7+GtbYCte4OCsbdChBg47x9nmP +gb+eSfk1r+33mQLYMFSeBLxDLwz/mDbEIsELFYNnvNrxtG5oVnGT8j+sgKdUg1wu +FQdbXVYjlwKBgQDErc8pUZTtjlZ+4d1S8GuTeGeYVanXBmrx8WXM3c9aPNq15kdF +kTVztTq/WBfOajXpgxrX3Lf+lNWSzUoe1s3vsATWbGNpQ+6yASJ1i1pn251ftWG+ +OfJi66M2TWZyw5A9zGNktIJzVUtmg+NXN/TXN2RVm46LBst9c+CxeL3C3QKBgCuL +YDYtdT/M1PfjcJ+NMw0h4DQ3MiTG96bzXAyQT2AoKI21Fuup9FAZegM7qixS6Q32 +MlZlZ5Tv1cnUVbpGWbf0KQXAAmSW54LDC/RgWCEb2cHeO1O/plxjlerwE8vRsS2F +X740aIJ5keP/zwuJTu24Ct28zMgi9gRUJxam5o8lAoGBAM12x2ZYNjp5XxVbHT67 +u2qSBmStXrAOZk3ojJKPP4gYa5S8APA+T1z0kiCV30NM2Ctcfhj77XBXJ2BXxpuj ++CPCufO3vXUZgAW7P8B3YReBwL71lF6Zst1LklxFuif0OCp4QyPpeXZOFV0Ka1uA +Upj2Em5jZYrjmGo9l0GPT8za +-----END PRIVATE KEY----- diff --git a/httpbin_server/docker-compose.httpbin-go.yml b/httpbin_server/docker-compose.httpbin-go.yml new file mode 100644 index 0000000..3f1323e --- /dev/null +++ b/httpbin_server/docker-compose.httpbin-go.yml @@ -0,0 +1,24 @@ +services: + httpbin: + image: mccutchen/go-httpbin + container_name: httpbin-go + restart: unless-stopped + ports: + -

Replace extract() with cast() for URL type checking to avoid PyErr creation on type mismatch (client.rs, async_client.rs) - Add frozen attribute to immutable types URL and QueryParams to eliminate runtime borrow checking - Add freelists to hot-path types Response (64), Cookies (64), and QueryParams (128) to reduce allocation overhead - Add JSON buffer pre-allocation based on object size estimate - Use is_instance_of() for Headers/Cookies extraction to avoid PyErr creation on type mismatch All 1406 tests pass. Performance remains competitive with requestx being 77% faster than httpx in sync mode and 141% faster in async mode.
