Hy ,
it's all a question on the Hardware and fine tuning Network , Server ...
we also have Transfer rates >25 MB/S into AFS in our Stonehenge Solution

I've never seen anyone claim transfer rates anywhere close to this with
any
brand of AFS (except for the testing that umich did ~10 years ago
bypassing
the cm and using dual paths).
Did you hack the client or server or do anything special to see this
speed?
Cheers,
Stephen
