Your guestbook opened pretty fast from my end. It only took 3 seconds! Perhaps you already fixed the problem? Have visitors complained? If not, I would suspect the problem might be with your computer. Are you performing regular maintenance? After doing a lot of work, the hard drive needs defragmenting, delete cookies, temp files, etc. Norton Systemworks is a good program for this stuff or Windows has a built in defrag.

Page loaded normally here. I would try your guestbook again if I was you and if it's still slow then try deleting all your temporary internet files as well as cleaning up your system and doing a defrag.
