feature request: update for imagor and thumbor

[liudongmiao]

1. thumbor docker support THUMBOR_NUM_PROCESSES
   https://github.com/MinimalCompact/thumbor?tab=readme-ov-file#quick-start
   docker run ... -e THUMBOR_NUM_PROCESSES=xxx or so

2. imagor docker support avif speed now
   -vips-avif-speed 9 or so

And in my test with wrk, it seems imagor and imgproxy has the same performance, and multi-process thumbor (python) bench +10% than multi-thread of go. (wrk requires lua script to avoid url cache)

Hey @liudongmiao!

https://github.com/MinimalCompact/thumbor

Oh, my bad. I saw their Docker Hub but the Thumbor version there is pretty outdated. I didn't realize they publish images on GH Packages now.

I'm aware of Thumbor's multi-processing mode, but I intentionally didn't use it. Multi-processing is indeed more performant than multi-threading in tasks like this. However, it's not necessary to have a multi-processing mode in the tool itself. Having a Docker image, you can easily run multiple replicas of a server and load-balance requests between them. So it would be not fair to use multi-processing for Thumbor but not for imgproxy and imagor. So I decided to not use it at all.

Oh, neat

And in my test with work

Can I take a look?

@DarthSim After switching the dataset from our single picture to DIV2K dataset, the result changed:

1. png to webp without fit-in, imgproxy > thumbor > imagor (less than 10%)
2. png to webp with fit-in 1024, imgproxy >> thumbor >> imagor (almost 20+%)
   I'll look into imagor to find the difference, why the same libvips cause so much difference in fit-in cases.

The wrk script is like this:

local tid = 1

function setup(thread)
    thread:set("id", tid)
    tid = tid + 1
end

function init(args)
   counter = 0
end

function request()
    counter = counter + 1
    if string.find(wrk.path, "%%3F") then
        path = wrk.path .. "%26c=" .. counter .. "%26t=" .. id
    else
        path = wrk.path .. "%3Fc=" .. counter .. "%26t=" .. id
    end
    path = string.gsub(path, "%%d", (counter % 100) + 801)
    return wrk.format(nil, path)
end
