Again, unless you have a very specific need to turn it off, like experimenting with UMLs, you *don't* want to turn it off. You *will* experience a nasty performance hit. Cache and buffers do go away if you're actually using the RAM; only what hasn't been used in a long time gets swapped to disk. Even with 128MB of RAM, you'll lose performance by disabling cache. Remember, your RAM accesses faster than your hard drive, all cache does is hold on to the most recently used data in the part of RAM that isn't being used for anything else at the moment. Cache is a very, very Good Thing. -- Paul Johnson baloo@ursine.dyndns.org http://ursine.dyndns.org/~baloo/
