Getting Slow

Ok there are several reasons this may be happening. Seeing as how thousands of people use WWF, I doubt the problem is there.

I suggest contacting your host. The most likely source of the low performace is a saturated web server or database server. If you run your site on a budget host you may be shareing your web server with a few hundered other sites, the same goes for the database server. Any one or more of these sites may be using more than thier fair share of server resources causing your site and all other sites to grind to a halt. The host should be able to tell right away what the resource constraint is.

I suggest bugging the sh*t out of your host to find out what the resource limitation is. And if they are not able to answer that question to your satisfaction, change hosts.
