Thanks!

 

Yes we enabled "posix sems" and we are observing the difference.

Yes posix sems will imporve performance a lot. Just make sure your os
supports them for locking between processes (if you're on linux it's ok).
Also the default "fast_lock" work very well if you're not doing time
consuming stuff inside them (like db lookups).

sys v locks are very slow.
