  I wouldn't call it crappy by any stretch...It's a damn fast bus with
plenty of bandwidth.  But yes, faster buses with more bandwidth do

  My point?  I can get an R10K Indigo2 for less than $1000.  I can't
touch an Octane for less than FIVE TIMES that cost.

  To me, the real appeal of the Octane is its multiprocessor
capability.  At this piont, my R10K Indigo2 is fast enough that most
compiles don't even give me long enough for a bathroom break.  That's
plenty fast for me (an acknowledged speed demon).

  I sure hope so...
