A little extra info – this site has a few thousand posts. Also, the test I did without plugins was with the plugins disabled. I’ll run a test on a bare install of WP in the morning to see how that does.
Hi,
You will need to tweak MySQL server settings so that it can accommodate more concurrent users. MySQL connection rates can be improved by either adjusting MySQL settings, or providing more memory and processing power to the overworked server. Query caching and proper indexing can also help to improve MySQL performance. Refer following guides to tweak MySQL server for big number of concurrent connections.

Thanks,
I used the Percona tool for my.cnf config but the performance doesn’t appear to be improved. I was able to crash the server with a load test on a fresh install of WP so that at least reasonably rules out an issue with the install.
Mysql is still maxed at 200mb of memory usage, shouldn’t that be changing? The database size is around 100mb.
This is what I used in the config file: http://pastebin.com/h0Q2TCTG
Mysql is still maxed at 200mb of memory usage
you can try bumping it to 2gb or something and then test it. also i wasnt able to acess New relic Screenshots
Sorry, there was a blank page in the notebook. View with this link.
How would I bump up the memory to 2gb? The generated config file from the Percona tool should have increased it past 200mb but it appears to have not.
this article has some good points beside links posted by accuwebshotsing above
http://www.ewhathow.com/2013/09/how-to-increase-mysql-memory-limit/ experiemnt with them and select the one’s which works best for your website
also your relic screenshot doesnt display much load. CPU was 50% at 100 concurrent users and RAM wasnt’used much either.
