We have a Local area vaxcluster with a Vax 780 as a boot node with
and a micro-vax II and incurring a peformance problem across the cluster
The 780 has 3 Ra-81's and the micro-vax one for local paging and swapping.
All our applications programs and data are on the 780 disks.
The problem surfaces in this nature. When we run a I/O type job on the
micro-vax the Interrupt stack on the 780 goes to 60-70% of the cpu cycles
If a cpu intensive job ie compile/links is run on the micro-vax the effect
is not as great. Has anyone else experienced  a similar problem? If so any
suggestions to correct it.
Thanks in advance
