I run a number of sites on my own dedicated server. The specs are: Dual Processor, Quad Core Xeon Clovertown 5335 4GB RAM Seagate Cheetah 15K I recently had them do an OS reload on this server and moved both the OS, mySQL and files to the Cheetah, utilizing the second drive for backups only. I run a number of sites on this, none of which are what I would say heavily trafficed. I have an IT group that manages my servers and they handled the migration, etc. My concern is that since the move, things have been dog slow. Both the front end of the sites and backend. These guys are great for support issues, but aren't able to deal with slowness -- since there are so many factors which could contribute. There are times when the site's performance is ok, but I'm confident that something is off. What's the best way to troubleshoot a speed issue? Are there any reputable companies whose primary service is to optimize sites? Here are my Android forums experiencing issues. Would love any and all feedback.
