I have a motherboard which has 8MB with an 8KB internal CPU cache, with a
486(DX)33... right now I have 16.59 Bogomips, and I have another 8MB SIMM
ordered... How much of a speed hit from undercaching should I expect? What
is a good "main_memory/cache" ratio?

Yeah, you think you do know, but I doubt it.
When you sit in a shelter with bombs falling all over.
And the houses around you are burning like torches.
