There are lots of factors involved here Olu.
It's almost impossible to answer this question with so little information. And frankly it'd be hard to answer in the abstract without specifically looking at the server etc.
So, there are a number of basic things you can do.
post the site address. From that people can determine whether it's slow from their location. This helps to determine if the problem is the server, or perhaps your client machine/network.
also tell us more about the setup. Is the server a virtual machine? how much ram is it allocated? What percentage CPU are you using? Where is the server located?
Cheers
