 Replying to [comment:9 Andrey <nikolay@…>]:
 > Unfortunately, my first project where the problem is reproducible is
 really time critical module. It is a reason why the performance issue with
 generic implementation has been found in such little time period. I have
 made some tests on 1.52 and found that from the performance perspective it
 is better for me don't use upgrade_lock at all than use generic
 implementation of shared_mutex.

 for the fix for this issue. But if it will not be fixed till end of March

 shared_mutex

 This is an interesting information. BTW, have you tried 1.45? Do you know
 the first version which introduced the regression?

 I can not ensure you when this will be fixed but the fact this is a
 regression would surely help.
