Subject: dosemu performance issue
Date: Thu, 03 Apr 2003 20:27:25 -0800	[thread overview]
Message-ID: <3E8D09AD.1050902@arnolds.dhs.org> (raw)

Howdy:

I've been trying out dosemu with an atmospheric model, compiled with 
Lahey Fortran and their 32-bit DOS extender.  I tried dosemu 1.1.3 
with freedos, and the Fortran app bombed with various errors (array 
out of bounds, etc).

Using the latest dosemu (1.1.4) with the latest March 2003 patches, 
along with the OpenDOS 7.0.3 kernel, the app runs (at least one 
scenario) but it runs very slowly.  I'm running on a dual-xeon 1.6 
GHz with 1 gig RAM, but it runs slower than on a single cpu box of 
half that speed.

Any tips on performance tweaking dosemu for this setup?  Yes, I'd 
rather run the code native, but it depends on some proprietary libs 
right now...  I don't currently have the source either, but I might 
be able to get another build if I had some feedback on tweaking the 
Lahey config.

Thanks in advance for any tips.

Steve Arnold
