Hi there,
I'm afraid it is impossible to even start guessing on the problem, when the only description we have is "it used to run fast, now it is slow" :-P
Please provide a bit more information, like:
What version of Umbraco are you using?
What does your hardware setup look like?
What kind of database are you running on?
Is it a dedicated server, or shared hosting?
How many sites are running on the server, and are they using their own or sharing the same application pool?
That will give us a place to start.
Best regards,
Soeren Sprogoe
