The answer depends on what machine you are emulating and with what
operating system. Something like a VAX with OpenVMS has a lot of
tuning parameters within the operating system for balancing batch and
foreground priorities. Most systems that had simultaneous batch and
interactive operation were se
One of the issues that I have run up against running OPENVMS on simh is that
the tuning parameters for the OS are not optimal for todays high speed disks.
If you run a IO intensive application (like synching mirrored disks under VMS)
the IO operations can easily chew up all of the emulated cycle
