The Second Life browser. I was able to tweek some of the cache and connection settings to get a more acceptable performance, but despite that, it looks like it is not using the disk cache effectively and insists on downloading content that should already be in the cache.
Since the latest browser update, not everything is rezzing, or it seems to be taking waaaaay too long. My disk light is going crazy! I tried clearing the cache, but it hasn't changed anything. Suggestions?
