MDEV-5081 - Simple performance improvement for MariaDB
do you know if we ship any binaries with fast mutex (-DMY_PTHREAD_FASTMUTEX)
enabled or officially suggest it? What was it's intention and what loads it was
supposed to make faster?
I'm trying to understand if fastmutex is worth fixing. It looks like duplication
of PTHREAD_MUTEX_ADAPTIVE_NP, so we have double spinning when they're enabled.
According to my recent benchmarks it shown worst performance.
