Hi all.
We are facing a very strange scenario. We have two mysql-instances running on the same machine, and they had been running functionally fine since about 6 years or so (catering to millions of records per day). However, since last few days, we were experiencing some elongated slowness on both the instances. So, we decided to "OPTIMIZE TABLE slow_table" on both the instances. We first ran the command on one instance. That speeded up things massively (select count(*) that was earlier taking 45 minutes was now running in less than 3 minutes). We then ran the command on the second instance. However, that seemed to have no effect. We ran the command again (on the same instance); again it had no effect. What could be the reason of this strange behavior? Both the instances run under fairly the same load, and both instances are mounted on the same partition (obviously, all the directories are different). Hoping for some light on this strange issue.
