Could it perhaps be a canonical case of Linux build with low CONFIG_HZ such as
100 or around?

And what version of VMS are you running? Different versions of VMS have
different idle characteristics..

Hi Priya,
This is one of those “it works for me” cases. Idling works fine for a VMS
guest on my fc18 x86 test system.
What is the output of “SHOW VERSION” done at the “sim>” prompt?
What does your configuration file look like?

Subject: [Simh] Reduce CPU usage
Hi,
The cpu usage while running the emulator is shown as 97% to 99%. Is there a way
to reduce this?
And I tried setting the cpu idle but no use. CPU utilization is still high.
sim> show cpu
CPU idle disabled, model=VAXServer 3900 (KA655), NOAUTOBOOT
64MB, HALT to console
sim> SET CPU IDLE=VMS
sim> show cpu
CPU idle=VMS, idle enabled, model=VAXServer 3900 (KA655), NOAUTOBOOT
64MB, HALT to console
Host OS used is Linux. fc18.
Thanks,
Priya
