The workaround is to abandon using VP/ix.

VP/ix does the best it can under the constraints of an 'operating system'
which based its modus operandi on the assumption that all hardware
was at its disposal all the time.

Xenix' formidable task is to share that hardware and time slice the
software operations in such a manner as to prevent the DOS
task from consuming all the resources of the system.

I don't know the technical details of how it is done, but the
keyboard lag you notice is commonplace. I have grown to live
with it, knowing that I am getting something done in DOS
without having to reboot. That alone is time consuming, without
mentioning the loss of Xenix services while running DOS as
the sole task on the machine.

I understand that these symptoms are either gone or much less
severe on a serial VP/ix job. Test that with a suitable
DOS application.
