It is really more about tuning
rather than fixing. And it is not
easy to do because one have to have
all the different test-cases around,
and people do not always provide their
progs for testing.
You can control the speed with
$_hogthreshold option of dosemu.conf
at configure-time, or by a "speed"
command at run-time.
Dosemu is trying to do some guesses
about a CPU usage itself, but right
now it doesn't work very well. It
is necessary for dosemu to at least
calculate the percentage of CPU
power it gives to a DOS task - right
now it doesn't do even this.
It was rumoured that the DOS program
called "tame" does a great job at
calibrating the CPU utilization of
a DOS task under a multitasking system.
You can try setting $_hogthreshold=(0)
and use "tame".
