What do you means with this?
Normally, on a diskless workstation, there is only one user doing his
work (even if it is a Unix machine), like on every usual desktop pc. So
with sufficient amount of RAM in the client machine, a memory cache of
about 10MB should be ok. And normally, should speed things up, compared
to disk-based cache.

RAM based filesystem is ok (NFS mounted root was just an example), but
with a disk based cache, I don't have a diskless workstation anymore. So
I could also boot from that disk.
