I'm interested in this, too.  _Personal Workstation_ [nee _MIPS_] a
few months ago [January issue?  I thought I had it at my desk, but I
can't find it now....] had a long detailed series of articles on
the 320, one of which said they really sucked air doing serious
multi-user work.  I copied the articles and gave them to my IBM
salesman, who's looking into possible answers/rebuttals.  It was
unclear from the article whether the problem was inherent architecture,
cache size (which would be somewhat remedied by larger cache on xy0,
y >= 3), or AIX (which could at some point be fixed).

It's necessary to note that _Personal Workstation_ could better be
named _PC Hotrods_, and they may have some editorial bias in favor
of not giving their Everex 486-using readers bad cases of RS/6000-envy.
But the numbers they published were disturbing.

This may all have been discussed before I discovered that this
newsgroup was where the RS/6000 stuff got posted.  If so, I apologize
for bringing it up again....
