To view the usage of the individual key buffers, I use “mysqladmin debug” and then view the error log.

Hi Peter,

How can we monitor performance of multiple key caches, like for monitoring global key cache we use “show status like ‘key_read%’; ” but how i can see same information for new created key cache.

Thomas,

It is hard to explain all the cases when one or another problem may be affecting you. I try best I can when possible. You are also always welcome to hire us to help you to understand what problem you’re really running into.

Hi peter,

thank you very much for all your valuable tips! I did not even think the KeyCache could be a problem.

But I wonder how to find out if I am hit by this problem or not. Does “For CPU bound workload” mean that I should have a look at this if the CPU usage on my database server is high?

Maybe it would make the articles even more useful if they started with “You should look at this if you have this problem: …”.

Best Regards
