Nevermind, I've got it.
When you try to execute something, scan_dir scans all the files on your
path and on your current directory searching for it.
Even more, it scans multiple times searching for different name
combinations (exe/com/bat and with different capitalization), and that's
what causing
huge bandwidth consumption and stalls when you're on a big directory.
Luckily for me, as I said in another mail I'm mounting the remote novell
partition with ncpmount that makes all acceses to the mounted device
case-insensitive, so I just made scan_dir return true always, and now I
think it determines
if a file it's there or not by stating it in find_file. I have
encountered no problems with this yet.
Could you explain this a little more... It seems that you have found the
reason why FreeDOS is slow sometimes.
Maybe that scan_dir could be re-written so as to scan only once ant test
all name combinations for each file in turn.

Another thing, I don't know if this is the proper place to ask for it,
but I've found that dosemu doesn't work right with dtach.
When you reattach you simply get a black screen and all the text,
windows, pictures, etc are gone. I can't use screen because for some
reason some programs just hang when they're executed in dosemu inside a
screen, but they work flawlessly in dtach. It would be
great if you could do something about this. To get around it I added
this at the end of sigwinch:
SLsmg_touch_lines(0,vga.text_height);
SLsmg_refresh();
It does work now, but I know nothing of slang and the docs say you
should not use SLsmg_touch_lines, so it has to be a better way.
It would be great if in the next version dosemu and dtach could get along.
