Performance

How to find the site performance, there is a tools like

YSLOW, Speed traker in google

that shows the speed of the website.

I have done a php project on LMS with Zend Framework, Everything is in live.

When user post contents for a subject that may be size 200K and submitted to the server takes too slow. Sometime server may get DOWN.

I login to server(PUTTY) and checked i found that there is more resource occupied in my server. It uses full memory on the server. When i cleared the resource the site loads well.

Site is in Dedicated server with 3 more domains with 4GB Ram. Because of this LMS website all the website gets down.

I need to check what is wrong in my website. How do i Start?

I have a site-to-site VPN set up with two SonicWall's (a TZ170 and a Pro1260). It was suggested to me that turning off encryption (so the VPN is tunneling only) would improve performance.
