Hi recently upgraded 5.5 to 5.6 and have noticed High SEMAPHORES round, waits, os waits.

Im unsure of why this is happening.

Hi,

Can you provide some more information? like

  1. steps you have taken while upgrade your server from 5.5 to 5.6?
  2. Error log
  3. Give exact version of 5.5 and 5.6 (i.e 5.5.x to 5.6.x)

Also im seeing frequent stalls with queries taking more time than milliseconds, even commit’s.

Steps.
Shutdown mysql;
remove old version 5.5.29 via yum remove
install new version 5.6.19 via yum install
run mysql_upgrade
change TEMPORAL Columns for Datatime with ALTER FORCE.

I have RAID 10 with BBU, 2 CPU with 16cores, 32(virtual), 32 GB RAM
