Here are the allocation worker changes.


Hello mark,  thanks for you answer

The biggest performance commit should be aa292847, which limits the callers to the worker.

Yes. This is the case :

3.4.39 with aa292847b9fc6e187547110de833a7d3131bbddf applied gives full speed again, at least on this very specific test. Will try to have a more global view of the effects on other tests.

Thanks,
