Client cacheing is turned on by default in SVR3.1  It can make a
tremendous difference in performance if your application's file
accesses are well localized.  We have seen cases where it actually
slows things down because the cache invalidation dominates.
Fortunately, it is possible on a per-connection basis to turn it off.
The performance difference can be 20% or more.
