I think you've answered your own thing here. DOSEMU doesn't magically give
you any more CPU. IF you application is CPU intensive under normal DOS it
will remain CPU intensive (and in fact use *more* CPU) under DOSEMU.

There are some optimisations that can be made, but they depend upon the
software and the environment. For example, hogthreshold can be changed. If
using X then the update interval can be changed. You may be running into
memory issues depending upon how much memory this task requires and what
you have told DOSEMU to allocate per user.
Nobody but you knows if that machine will handle the load -- only you know
what the software is, how much of the resources are needed per session,
etc.
