Optimising Scripts and options

I have been asked to optimise my settings by my host as it has caused a problem on the shared server i am using.

I found a guide about it here, but i have lost where it is now.

Could someone please point me in the right direction?

thanks

What is your host? You should ask them how many sites are currently hosted on the server containing your account as well, for reference on the total load.

Please be advised that some hosts have a habit of abruptly shutting down accounts they claim are causing performance issues. As a backup plan, if possible for you, you should consider moving to a new host.

Yeah, i'm using hostgator and get a mixed response when asking people if they are as good as they claim to be.

thanks for the info, i will have a good look through.
