Folks, Here are some further observations on memory usage with my vanilla 8.0 install. After the initial swapping I observed I upgraded my main memory from 512MB to 1GM. 1. Most applications run noticeably faster. 2. My most demanding application at this time is Matlab and with 512MB of ram I was maxing out and going to about 20MB of swap. With 1GM of ram I do not exceed about 400MB of memory usage with the same Matlab scripts. This is curious. Does that mean I was swapping and maxing on memory due to memory fragmentation and the virtual memory manager? If so is that reasonable that 100+ MB was "unuseable" with 512MB ram?
