I have been running Warp OS/2 running on real Windows for Workgroups 3.11 and MS-DOS 6.22. I have noticed that over time everything run more and more slowly. In particular there seems to be ever increasing disk I/O as programs (especially windows ones) are loaded or swapped. Does anyone know what is happening and how I can reverse this slow down? Regards, Richard.

Just a guess...but how about fragmenting the disk on which your SWAPPER.DAT file is? You may want to check that out. Victor A. Wagner, Jr. CFO Metadigm, Inc.

You could have lots of little objects running around in the background. :) Try running System information tool, in the memory bit it will tell you how much memory is locked by OS/2. Shouldn't be too far off 2mb discounting your cache size, when you have nothing running. If you set the initial size of swapper.dat to 32mb or something, then it probably won't have to grow, which is faster. There is also a way to set whether each win/dos program you run is a true virtual machine or just another session of the existing one. I can't remember how to change this as I am not at my OS/2 machine, but I believe that you can tell by looking at the window list. If successive windows programs are indented under a 'WIN-OS/2' heading they not real VM's. Real VM's are much more crash-proof, but take heaps more memory which would make swapping more necesary and slow down restricted RAM PC's. Can't even remember where I heard this, but I guess it's something to look up. Well, that said I'm sure you've already solved your problem, and it was a tiny insignificant thing (turbo switch? :).
