It is hard to say what your bottleneck is without knowing your system
configuration.  As a first guess, assuming you are using the RS/6000
in stand-alone fashion, the problem might be that the system
buffer cache has not been tuned properly.  The default for this parameter
is only 20 pages (80KB).  In almost all cases, this parameter should
be increased to something more substantial (like 1000 pages).  The easiest
way to do this is to use smit (System Environments; Change/Show
Characteristics of Operating System), as root of course.

If you are remotely accessing the RS/6000 machines, the problem could
be with your network configuration, or your X terminal configurations.
If you are using AFS, try increasing its cache size.
