Re: Fine-grained locking for POSIX local sockets (UNIX domain sockets)

Fixing one of big lock contentions is not enough, you have to fix them all, it is easy to see that a second contention becomes a top one. :-)

So I guess the real question is: do we want to merge the UNIX domain socket locking work? The MySQL gains sound good, the performance drop under very high load seems problematic, and there are more general questions about performance with other workloads.

Maintaining this patch for a month or so is no problem, but as the tree changes it will get harder.
