Server Load

[markevanvic]

Hi,

I have a dedicated server with specs below:


Number of Processor 4: Intel Atom CPU 330 - - 1.60Ghz
2 Gigs of Ram
1TB of HDD
Running on Centos 5.6 i686 Standard
Cpanel/WHM
Apache Streaming
100Mbps Port

The server load is always running around 25-35 when video conversion and there is around 80-100 User's Online the video and pages are loading too slow,

What will you suggest to make it run smoothly and fast, Lighttpd is not supported by Cpanel so it is not a choice for me, as well as LITESPEED (saying that video conversion wont run), will upgrading the Ram will make the server Run Smooth, I am planning to tell my host to make the RAM 8G, and changed also the processor if applicable, because there are the one who get the server for me, defends on the load i have when i am using shared hosting on there server too

Hope for your suggestions

Regards,
Mark
