Hi,

regarding the hardware implementation of a 4KE (r4k style mmu
if I remember) I'm wondering about the performance difference
when the TLB has 16 pairs of entries (covering 128KBytes of
data) or 32 pairs (covering 256KBytes).

Does someone have a useful advise regarding the `nice spot'
for TLB size?

Sincerely yours,

E.M.
