I have tried various settings of hogthreshold, but I can't prevent a
certain program (GrandView) from grabbing all the CPU when it runs.
Is there something I can do about this?
I'm running dosemu 1.0.2 packaged for debian woody.
2.4.9 kernel on Linux.
AMD Athlon processor.
The program is a full-screen character mode program (an outliner) from
the DOS era. It does respond to the mouse, which I suspect is the
problem (that is, the program responds to the mouse by polling
continuously). I would like to retain the ability to use the mouse.
When I run it under MS Win 2K it consumes almost no CPU.
By the way, I find the description in README.txt a bit confusing. It
says:
As you would realize at the first glance: DOS will not have the the
CPU for its own. But how much it gets from Linux, depends on the
setting of `hogthreshold'. The HogThreshold value determines how nice
Dosemu will be about giving other Linux processes a chance to run.
$_hogthreshold = (1) # 0 == all CPU power to DOSEMU
# 1 == max power for Linux
# >1 the higher, the slower DOSEMU will be
Does this mean that 1 essentially is the same as setting the value to
infinity? The discontinuity of scale is a bit surprising; based on
the description of >1 I would expect 1 means "DOSEMU runs as fast as
possible".
Thanks for your work.
