Terminal Services vs. Citrix

I need a pointer to a document (or several) comparing Citrix MetaFrame XP to Windows 2000 Terminal Services for the areas of resource utilization; both networking between client and server, and server overhead resources per session.

I've seen a number of comparisons on features, but nothing (biased or otherwise) on utilization or performance.  I need something relatively recent for Windows 2000.

I don't think that you are going to find a document that compares the two products.  MetaFrame enhances the Terminal Server experience.  You have to have TS in order to load MetaFrame.  

I guess you could make an argument for the client pieces that each product provides.  MS's TSAC vs. the MetaFrame client, but there's not going to be much to compare.  They are both very thin in regards to req'd bandwidth.  MetaFrame's client is based on a proprietary protocol, ICA, whereas the MS client is based on what MS calls an open protocol, RDP.

Which is better?  The only way to find out is to do a comparison in a lab environment on the applications that you want to run.

IMHO, the basic question when comparing the two is: will I need to access resources on the local computer (i.e.: the terminal), and do I need loadsharing.

As I see it, these are the two major reasons for choosing MetaFrame over Terminal Server. Of course you will get the simple installation running it all via http/java, but that's only a true benefit when you reach large networks.

If your users have stuff like PDA's, need to use local printers via their own pc and suchlike, there's really not much choice, - TS does support somewhat, but it's very limited compared to MetaFrame (and this is not a commercial ;-)

Kind regards,

I've seen feature comparisons before.  That's not what I'm asking for.  Adonis gave me some good pointers before (thanks again).

What I'm specifically looking for here is a comparison of the network utilization levels and the CPU utilization levels between the two products.  We've been told that MetaFrame has a lighter network footprint for the same applications, hence works better over lower bandwidth, higher latency, networks.  That's just heresay at this point.

Same story for CPU and memory required per session on the server for hosting applications under either environment.  We recognize that you need WTS licenses for each&every Citrix session, but that may be a licensing issue, and not because one layers on the other.  If they do layer, I would expect Citrix applications to take up more memory - I can't say about CPU.

That's what I'm looking for.
