here is my server info
Processor: Intel core i5 750
Memory: 16 GB DDR3
Harddrive(s): 160 GB SATA 4 x 2000 GB SATA
Connection(s): 1000 Mbit
Operating system: CentOS 5.7 64 bit

PS - i have raid 0 on the 4*2TB hard disks

the load is not high --- i5 750 has 4 cores and your load is around 4.

please paste the output of "top -c" for more info.

current load only 1~2, your customer should not feel slow at all.

capturing output of "top -c" and lsws real-time stats on the busiest time, should be most helpful.

i been checking the server from morning, when i get close to night the speed of the download get slower, the time websites take to load up is higher and when i try to ssh to server or open Cpanel it will actually take ages
PS - litespeed admin area working perfectly normal
here is another "top -c" result, i'm not even sure if it's a problem with web server anymore =/

when i try to ssh to server or open Cpanel it will actually take ages

in such case, please check:
#sysctl net.ipv4.netfilter.ip_conntrack_max
#sysctl net.ipv4.netfilter.ip_conntrack_count
