vax 785 vmstat

[salmi]

i have just recently brought up ultrix 1.1 on a vax 785.  after running the
recently distributed dhrystone benchmarks on the new system, i was appalled at
the outcome, somethint like 50000 passes in 102 seconds! (480 stones/sec?)

running vmstat on the system gives the following results, with one user on the
system...

the interupts per second are averaging more the 5000 on an 'idle' system.  our
loaded up vax 750 running 4.2 gives the following results from vmstat...

all of the ports had been shut off on the 785, thinking that a runaway getty
may have been the culprit, but no change was evident.  another thought was the
DEC ethernet board may be the bad guy.

anyone got any clues/ideas?  the 785 must be fast, as the response time was
fairly fast even with the 5000+ interupts/second running rampant.

any/all ideas would be appreciated.  please respond directly to me at:
