I'm trying to run two copies of a large app built using djgpp under
dos, and it's only running at about half the speed that it runs under
linux.  In addition, the swapping behavior seems much worse.

The app does a tremendous number of small mallocs and frees, and it's
also possible that I'm somehow producing 16-bit code under dos and
32-bit code under linux.  Are these likely to be the source of the
problem?  And if so, any suggestions as to how I might fix them?

Please respond directly to me, as I don't follow this group.  Thanks!
