hmmmmmm, would those work? Those suckers are cool, but expensive....
It would be nice if NeXT would either beef up the cache allocation, or
make it settable via a file... It would be cool if Mach did what
NetWare does... NetWare uses ALL unused memory for file, FAT, and
TurboFAT caching. A 32-meg NetWare server just cranks, even with a
LOT of disk access going on. So if Mach turned all available memory
into disk-cache and then released it as memory was needed (until the
disk cache reaches a certain point), we'd prabably get more speed.
But Chris Lloyd is right... the SCSI drivers (and many more low-level
drivers) seem to be pretty screwed up.
