WampServer

I have just installed WAMP5 to help me with some PHP development and am very impressed. During installation I was asked if I wanted to start WAMP automatically which I did and it also detected Firefox and asked if I wanted to use that as my default browser. I am now finding that all sites are now loading quite slowly into Firefox. Is this because I asked WAMP5 to always be running as a service?
