I've mentioned this before (and got some negative feedback for it
as everyone is focused on the CPU, not I/O), but I think some tests
that measure I/O performance using RMS (which will force a range of
mode transitions including through executive mode) may be interesting.
To make it a fair comparison, the I/O could be to a RAM disk so that
VMS overheads only are being compared.
