What is jLAN? I've not heard of it.

Is it not possible to boost the server hosting this as much as possible?
ie faster CPU, loads of RAM for caching files, etc.

WAN optimisation is network latency related, and if your servers are
local and on 10Gbe it's not going to help much.

Samba will take as much RAM and CPU as you throw at it, not sure about jLAN.

Putting anything that caches in front of a R/W CIFS server is a very
risky proposition. Locking is probably the biggest. Caching is built
into the protocol, search for "oplocks" for instance.

BWT, Samba can do clustering now - search for CTDB.
