- I put OS/2 on my no-name 486/33 box last week. The installation worked
- smoothly, and I haven't experienced any problems running my applications.
- However, all of my compute-intensive DOS applications are only running at
- 50% native DOS speed when launched in a full-size screen under OS/2. The
- latest OS/2 FAQ says to expect 95-97% native DOS speed from a single DOS
- application running full-screen under OS/2. Does anyone have any ideas
- where the other 45% of performance went?
-
- A little more info: I only have 5 MB of RAM, but the problem does not seem
- to be related to disk swapping; I have watched the disk drive light while
- the programs are running and the hard disk is not being accessed. I have
- AMI BIOS dated 6/6/91; I've heard of problems with OS/2 and AMI BIOS but
- these don't seem to be performance-related problems. Any help from you OS/2
- gurus out there would be much appreciated.
