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.
