It's possible that you have a spider stuck in your web. ;-) Seriously, make sure you have a robots.txt file in the root of all of your sites with an appropriate stanza to keep them out of areas where they don't belong (this is usually the order entry part of the site). Not all robots will obey that file, but it should keep the noise down to an acceptable whine. Secondly, when you notice the slowdown, check to see what hosts are connected to your system (netstat works for both Windows and *nix or OS/X, don't know about classic Mac). See if you have lots of connections from a few IP's or lots of connections from all over. Thirdly, temporarily enable the Debug log (in the Preferences), which logs every single page requested, just prior to returning it to the client. Make sure you have lots of diskspace and turn the debugging off when you have captured enough to analyze (this _will_ slow your system down further, but it is very valuable information). Once you have a file, look at what is being requested. This will sometimes show where you have coding errors and it will also show if a single IP address is requesting the same thing over and over (an error in your logical flow that has captured a spider).
