I was on a customer's site recently and they demonstrated a problem with
an ancient DOS application running with Btrieve v6.15 Workstation for
DOS (Yuk)...

The application would load normally/quickly on P4-based systems,
however, the same app took about 20 seconds to load on Xeon-based
systems. Any thoughts?

I suspect this is all somehow related to the DOS4/GW 'shell' that
Btrieve is loaded into, but wondered if anyone has specific details
about exactly *why* it's slower?

Ultimately, I just want some hard facts to put in front of them. The
upgrade to V8 is pretty much a done-deal, we just need to give their IT
Manager some ammo to show the bean counters...

TIA,

I think I can think of some, but not the one you describe.

There is a Windows issue however that causes DOS apps to run extremely
slow on systems with a clockspeed above 2GHz. You should be able to
counter this problem by running the app in full screen mode, obviously
not possible when using Terminal Services or Remote Desktop - whatever
they want to call it nowadays...

I forgot to mention, the machines in question are part of a farm of
Citrix servers... all running the same version of Citrix, mainly on
P4-based (Dell) servers, with a few running Xeons.

Are you using IPX?
If so,try remarking the following lines at CONFIG.NT (usually in
c:\windows\system32\config.nt)
rem lh %SystemRoot%\system32\nw16
rem lh %SystemRoot%\system32\vwipxspx

Still you might want to check if it's the Windows fluke. You can only
do this at the console and it won't help the clients but at least
you'll know...

What OS / service pack is on the Xeons?
