Obviously, YMMV (your mileage may vary), but my understanding is that
operating systems (like *nix) are likely to balance the load better than
your average (i.e. MS) PC operating system. With the exception of specific
MP versions of Dec Ultrix which were brain-dead from the start. ;-)

I run RC5 as a service on an NT4 (SP5) box, and do notice a significant slow
down - at least enough that I switch RC5 off during working hours.
However, regarding installers, the worst culprit is anything that uses the
NT 16bit subsystem - e.g. MAPISP.DLL (as used by Outlook for example). This
effectively stop installers running until terminated, at which point they

See my points above. As I have suggested in the past, more effective control
over process priority would be useful in the NT version. Note, task manager
does not work, before anyone suggests it, :-)
