I currently use a disk cache on my 386/25. I had previously set it to 1 MB. However, this is ridiculously large (so as to be counterproductive). I downsized it to 384 KB. This is probably still much too large. I received a suggestion that 64 KB is probably a better size (since that is the size of hardware caches on most machines with hardware caches). That doesn't seem like a real good reason to me. So, I am looking for method(s) to determine what the cache size should be. As I said, I have a 386/25 (with 4 megs of memory). The excess memory is currently being used for a ramdisk. I believe this will be of interest to others and that many people will have an opinion on this, so please send e-mail and I will summarize to the net in a week (assuming I get any responses). Thanks in advance. -- Eric M. Boehm EMB978@leah.Albany.EDU EMB978@ALBNYVMS.BITNET
