I am just pointing out observations.As it turns out I think that WIN 95 does about the same job as WIN NT when allocating memory to its cache. Because it grabs about 20Mb for itself, this has a large negative effect on large hash tables on machines with 64Mb of RAM or less. Because of this I recommend that all computer owners have at least 128 Mb of RAM in their machines. With that amount you can allocate up to 90 Mb ( maybe only 64 Mb because of block hashing) of RAM without swapping. -- Komputer Korner
