Could anyne tell me about the performance handling of DOS in Win 3.11?

Could you be a little more specific about the question? What do you mean by performance handling? DR

I guess what I am trying to find out is how does DOS work differently in 3.11 compared to 95.

I refuse to get into a protracted discussion on why 7.x is worse (in many ways) to its predecessors. However, off the top of my head (and IMO): Allowing spaces and special characters in directory and file names. Elimination of several key utilities. Elimination of DOS help. Worsening of some commands, ie. sort.exe, and dir. Removal of the / switch in the FOR command. dir ??.bat now returns only .bat files with 2 letters, whereas previously it also returns .bat files with 1 letter. Some commands also get confused when there is or is not a space after it. DOS 7.x - takes some protected mode memory (forRegistry/configuration/others) and is much less optimized for performance than regular MS-DOS as it is used by Win 4.x as a bootstrap loader only. In particular it runs up to 2x slower over networks or without a disk cache. In any event, everything seems to be much slower in DOS 7.x than in 6.22, and in my experience, everything in Windows 4.x IS definitely much slower than in Windows for Workgroups 3.11.
