Ok. I am using a 1and1 linux shared hosting (boo, hiss - I know - plan to move to dedicated in a couple of months) The server is ULTRA slow. We are talking page load times of 15 seconds, it is like being up on dial up again. The server was running fine - untill a week or so ago. I have made few changes. I am worried that there is a php script in a loop or something - I have looked at everything I can think of. I have ssh access and I have tried running 'top' but this doesn't run for me (maybe as I am on shared hosting). Yes it could be another account on the same server - I have asked the host to look into this BUT I want to do everything I can in order to speed these pages back up. Thank you Brian
Echo the microtime at the top of the script and the bottom and in a few places in between. Then you can see which bits are taking longest.
The best way to see if it's you or not, is to rollback the changes you made to your site. If the site remains slow, then someone else on the server is hogging all the resources.
