Apache httpd not loading php pages properly.
I need somebody who is experienced in apache servers, that can answer my frustrating question. My question is, why do my php pages do not displaying properly? Weird things tend to happen when I repeatedly use my site(when one page after another is loaded in a short period of time), or if I refresh the page, sometime the pages don't fully load and just get text, or sometimes when I reload a page the images refuse to completely load. Also my server seems to be sluggish, it's load average is about 2 to 3 after a while. What can be the cause of this?? At first I thought it was Apache's HTTPd 2.0 fault, but I then installed HTTPd 1.3 and the same things started to happen again. My server is an old Intel based pc, with a Intel Celeron 300a processor with 256 MB of RAM. Is it my hardware that's the problem??? What's the are the minimum system requirements to run a httpd server with php. By the way my php pages heavily rely on a MySQL database, because my site has a web interface to my file server and all the files are indexed on database (about 60 thousand file). I hope somebody can help me find a solution to this problem, because I really don't know what the source of this problem is.
Tnx in advance for your answers,
