Slow load speeds

I'm running a network of proxy sites using PHproxy on my dedicated server.
The server specs are as follows:
Processor: P4 Dual Core 3.0
Memory: 1GB
HDD: 160GB SATA
Bandwidth: 1,000 GB w/ 10Mbps port
Operating System: Centos


I also run some blogs on my server. I recently noticed that load time of the blogs is nearly 30-60 seconds. It wasn't like this before and I'm unsure as to what is causing this. It also occurs on one of my myspace resource sites.

http://www.samdaves.com/blog << the home page of this site loads fine but when trying to access the blog it just waits and waits and waits

http://www.layoutsmart.com/contacttables/Animals/ <<The homepage of this site also loads fine, but when trying to access pages that use PHP it doesn't want to load


Anyone have an idea as to what I could do to fix this issue?

Thanks in advance,
Sam

 

What version of CentOS are you using? If you are using 5.0 or below, there's probably a problem with the operating system and your ethernet card.

Also, what control panel are you using? I'm asking this because this'll help me link the problem to the loading speed.

 

Did you try to look in the apache error_logs or access_logs ? You may find some answers there.

 

WHM 11.1.0 cPanel 11.4.6-R13580
CENTOS Enterprise 4.5 i686 - WHM X v3.1.0

 

Hivelocity's support is trying to tell me it loads slow because it has alot of content on it. Pathetic. Its a simple blog ffs.

Error log is full of alot of File does not exist like the above.

 

Would it have anything to do with my PHP settings?

 

I resolved the issue by setting the php_include path.

stupid mistake on my part.
