Which versions of server and client are recommended for test of Win32 apps?

For testing purposes I need to simulate the behavior of 160 users on 4
Citrix servers running a Win32 app that connects to a SQL server. So
basically I need to be able to start 160 instances of the 32bit app, but I
only have one server to work as application server / Citrix server. (Quad
core Xeon with 16 gb ram)

I plan to install Win Server x64 with 4 virtual Windows XP clients each
running 40 instances of the app. I plan to dedicate one of the cores to each
of the virtual clients and 3 gb ram. This enables me to simulate scalability
with 1 to 4 Citrix Servers - each with 40 instances of the app and the same
processing power for each user. I know it is not exact simulation, but I
guess running the app 40 times in WinXP is less demanding than having 40
full user sessions on a Citrix server.

But is the above an ok approach? And is it ok to use x64 versions of Windows
Server and Virtual Server but only 32bit of XP? Anything else I should
consider? Please note, that the actual app is 32bit and is unable to take
advantage of multiple cores.

Thanks in advance

Peter

Hey Peter,

I'm not sure I understand what it is you want to test?

I mean running application, database and terminal services on the same
server doesnt test much in regards of load. - Furthermore if your test will
show you performance issues, it will be very hard to nail down exactly what
is causing it...

Especially if your running the Virtual Server 2005, as that will not allow
you to control the CPU's, which might be very usefull when talking terminal
services.

I would strongly recommend that you actually do the 40 user citrix sessions,
rather than having 40 XP clients hitting it. We are running both MS TS and
Citrix here, and we are seeing some funny results on it.

I hope that gives you something to work it!

Kind Regards
Jesper
