Subj : Taming some high-CPU usage DOS doors in dosemu2

I'm running my BBS in Linux and was initially using dosemu 1.4 for DOS doors, but I got dosemu2 working, which enabled TradeWars 2002 to run (TradeWars 2002 doesn't work with dosemu 1.x).  However, I've now noticed that some other doors that were working okay with dosemu 1.4 now are using 100% CPU with dosemu2 and are running/responding very slowly.  Some of those are doors I really wanted to work well on my BBS.

With Windows, there was a program I had used called Tame, which would do something to reduce CPU usage of a running process and make it more responsive when running in NTVDM in Windows.  I doubt Tame would work with dosemu though.  I'm wondering if there is a process-taming program for DOS programs running in dosemu, or if there are any dosemu2 settings that might help a DOS program run better and respond quicker?

I'm wondering if the issue in such DOS programs might be some kind of loop it's running that's taking a lot of CPU time.
