@@ -10,9 +10,10 @@ it's common to have processes rather than threads to handle large workloads.
 To handle this the client library can be put in multiprocess mode.
 This comes with a number of limitations:
 
-- Registries can not be used as normal, all instantiated metrics are exported
+- Registries can not be used as normal
   - Registering metrics to a registry later used by a `MultiProcessCollector`
     may cause duplicate metrics to be exported
+  - Filtering on metrics works but is inefficient
 - Custom collectors do not work (e.g. cpu and memory metrics)
 - Gauges cannot use `set_function`
 - Info and Enum metrics do not work
