I'm wondering which tools I can use to test load some PHP/MySQL programs running on a Linux system (Centos). Open sourced or paid ones. I have one site in particular (http://www.personals1001.com
) and it seems to slow down with more than 20 members. Not all the time but sometimes. I'm thinking that I can do some call stack trace using Eclipse debugger but I use another IDE which uses a different debugger. I suppose I can set up another environment specifically for Eclipse though.
But are there some good tools I can use just to install on my Centos server and then see how many users this site can handle?
I'd like to load test other sites too that are hosted on shared hosting servers (if possible).
