    Our pages have been loading slowly the last week. We've not made any changes in our website code. I've checked the database - very little has been done the last week in the DB , and the DB access is first class without issues. The pages used to load in 0.5 seconds . Even alexa rating showed it as such, but recently it's started showing about 2.3s+.

    I've made no tweaks or changes to the network. nothing appears in the error logs ( cpanel server ). I've gone through and optimised the mysql as best as possible. Nothing appears different in either systems with their raid etc.

    My setup -
    1 db + 1 web server

    both server spec
    8 core xeon 5410
    2 x ssd ( in db server it's 1 x mysql folder drive, 1 x system + in web - it's a raid1 )

    The machines mainly some PHP intensive websites. Two blogs ( optimised with w3cache ) and a kayako helpdesk. I think I need to optimise my PHP settings. Can you recommend something for me ? Or give any clues as to where the issues might be ?

    You really need to look into what is the bottle neck of your server when it is slow.

    could be CPU, memory, disk I/O, network I/O. check top, iostat and dmesg.
