It will be slow because of several reasons: 1) Disk access. Disk access is slow. Very slow. Fantasically slow. You can get information faster by using tin cans with string. Well not really... 2) Disk access. If you use too much memory, your application will page data to disk. This is a deathblow to site performance. It looks like you're using a shared hosting plan. They general hard-limit you to around 15mb of RAM that your application can use. So, I'd go find a better host if I were you. A virtual private server. If you absolutely need loads of disk space and bandwidth (you probably don't) then try DreamHost. They have a PS service which is basically a virtual private server, but it comes with DH's "unlimited + 50gb" plan for everything else. You end up paying around $25/month for a 300MB server. I host my site on a 512mb server through prgmr, which gets me 12gb of disk space but a full, dedicated OS on a very well-provisioned server. The other kind of slow which you are probably NOT experiencing is CPU bottlenecks, which is where your application is doing too much processing to efficiently serve pages. -- Registered Linux Addict #431495 For Faith and Family! | John 3:16! http://www.fsdev.net/ -- You received this message because you are subscribed to the Linux Users Group.
