Did anyone notice any performance gain while using Remote Desktop via Citrix XenApp 6.0 vs just plain Terminal Services on Windows 2008 Server R2?

I understand that Citrix offers a lot of great features but this question is just about how responsive and fast the Remote Desktop experience is in either environment.

The ping between server and client should be at least 150ms eg. distance should be more than 7000 miles.

Disclosure: I work with Citrix a lot, so I am biased

Citrix XenApp won't help improve performance of the applications as such - i.e., it won't increase the speed at which Office loads or whatever, that's not its job. However, it will almostly certainly improve the user experience overall by ensuring a consistent connection, improving mouse and keyboard response etc. In other words, what happens on the server stays the same - it's the ICA / HDX protocol which gives you the improvements.

I'll be honest and say I've not worked much with raw Terminal Services in 2008, and I know it's much improved from before, but I'd always edge towards Citrix where budgets allows.

Just remember that it does sit straight on top of Terminal Services, so it's always going to cost you extra.

Citrix really starts to shine over low bandwidth connections in particular (After all, that's its heritage), and they also have products such as Branch Repeater and Netscaler which are specifically designed for WAN acceleration.

You can get many Citrix products on evaluation if you sign up to Citrix.com, so I'd recommend you start there. While there's a lot of tweaking you can do with Citrix, the base install is reasonably straight forward if you follow the instructions.

If you could provide some more details on what you're going to be using it for, I'll happily give you my opinion.

Yeap, ICA is much better protocol than RDP on slow connections, low bandwdith, etc. This is perfect case where client should move forward because of the protocol only... Disclosure: I do not work for Citrix, I consolut for both technologies. –  Frane Borozan Dec 16 '11 at 13:16
