A friend was seeing a terrible response and tracked it back to Netscape's memory cache. He had a lot of memory and started out with something on the order of 16MB. By the time he was satisfied he was allowing less than ~2MB of memory cache, which is all I had ever allowed it to use. I seem to remember an affect on how much disk cache but that part of the memory has evaporated.
