Hello, 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 16GB 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 ?
