Thanks for the info Amos!

I am not completely familiar with how the DOS Emulation in NT works, but I would guess that the extra time could be 2000 Journalizing the write. This is just a guess, but it is slightly educated, since it is a well know n fact that Journalizing slows down file systems (ReiserFS, ext3, bfs issues)

As for how long it slows down, my guess would be that 2000 has to send the filr through the DOS Manager to Windows, which then saves the file using it's own method...thus causing a delay.

Unfortunately, I tend not to see slowdown on my system so I can't take anymore guesses.

I don't believe MemMaker agrees with the NT-based OSes. You may be able
to tweak the CONFIG.NT and AUTOEXEC.NT files to remove functionality you
don't need.

I've noticed that occasionally Win2K takes a long time to close files in *any* DOS application, but I've never been able to find a pattern to it.

In my K6/266, the delay is usually around 1-2 seconds per file - certainly not 6-7 seconds (unless this *is* the problem you have and you are closing multiple files).

However, this occasional delay when closing a file is not a PowerBASIC issue - it is the O/S close function that is taking its time...

If anyone else has any theories on this, I'd be interested in discussing it further.

Thanks!

PS: James - please do not shout! (posting in capital letters is considered by many to be equivalent to "SHOUTING!"). Thanks!

AGAIN, THANKS TOM.

THE SERVER "WIN2000 BOX" SHOWS FREE MEM OF 605 BUT I WOULD LIKE
TO DO A DOS TYPE MEMMAKER TO MAKE SURE EVERYTHING POSS IS IN
HI-MEM. I HAVE SEEN 630 ON NT4.X SERVER/WORKSTATION.IS THIS POSS
IN NT5 (W2K) ?

THE ONE TIME LOAD OF THE DOS EMULATION FILES SEEMS LOGICAL BUT
UNTIL I ACTUALLY STUFFED THE FILE COMMAND.COM MY DIR THE MOVEMENT
FROM ONE .EXE OR .PBC SEEMED TO TAKE 6-7 SECONDS - WITH IT IN
PLACE THE WAIT IS ZERO TIME.GO FIGURE..

THANKS

The delay should be a one-time thing as Win2k loads its monstrous DOS emulation files.
These are left in memory after the first load, unless you explicitly terminate it. Due
to how the NT memory manager works, "left in memory" does not actually reduce the amount
of memory available to your programs, so it is not an issue in that respect.

Using CMD.EXE instead of COMMAND.COM will not help the load time, but does give you
access to a more modern 32-bit command shell (with LFN support and other improvements).

Thank you: TOM HANLIN

The QuickEdit ON default was the problem..

The greatest support in the world - I now have a happy win2000
user in Athens Ga. (I am in Walnut Creek Ca.)

I assume that any problem of this type will also be in XP ?

Now, if I could eliminate the 7.0 second delay
(in the w2k desktop) using a std shortcut icon to my dos app
via command.com..

I think the cmd.exe may be the answer ?

sounds like the infamous quickedit gotcha:

Having a problem with a mouse routine that has been working in
every DOS and Win vsn up to ME incl NT4 (I still use pb3.00c )

The routine comes from Eric Olsen's DRAW application.

My latest installed user happens to have WIN2000 (nt5?) and the
mouse seems to have expired.

My mainmenu .exe is called directly from a desktop shortcut icon
and after a 7.0 second delay appears to run as designed except
for the mouse. (it is using the command.com that came with w2k
that I copied into my working dir. This eliminated any delays
within my application when using my secondary menus.)

Thanks in advance.
