Analyze site and rebuild Apache

My CentOS 5 server is running 2 Quad core CPUS (8 cores), and 4 gigs of ram but it often just hangs for 15-20 seconds on page loads with the server load averaging only around 3 or 4. Something in either the PHP code of my video sharing script (Agriya Rayzz 2.3) or the current apache build is causing the occasional hanging. I would like someone to analyze and browse the site for maybe 1 hour or less so they can notice the hanging Im mentioning. I'd like that person to help me narrow down the problem and if needed (if its quick to do) make the adjustments or re-install of web server. Possibly first start with a Apache/php/myql rebuild with just the bare essentials for Rayzz then look at error logs and troubleshoot from there.(current install has too many modules pre-loaded) I tried doing the apache build from WHM but it fails with an error code. I also tried easyapache from Shell and it also fails with the same error. I had to use the easyapache restore to get the site back up and running. Coder will need to build from source probably or maybe yum/rpm other way. The site is a video sharing site with adult content like a "you porn" but receives around 15k unique visitors a day. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
