The 35 kbit / s never seemed to be achievable.Īfter some phone calls with Citrix Project Snowball, we decided to embrace a project that focused on optimizing ThinWire within the ICA protocol and what we call since Feature Pack 3 now ThinWire Plus. On average, we came out of around 170 kbit / s. We had the h264 (Super Codec) compression already disabled because it caused a lot of high bandwidth and a lot of optimization applied in the policies, but we did not get the line under the 150kbit / s. The narrowest lines were 256kbit and there were about seven session running over, which equates to approximately 35 kbit / s per session. Unfortunately, this client had a number of low bandwidth locations. without tuning halfway this year we were at one of our customers engaged in a deployment of XenApp 7.6 Windows 2012 R2. This was evident at the ICA protocol, which was heavily optimized for GDI and triggering a higher bandwidth in Windows 2012R2.ġ. Since Windows 2012R2, Microsoft make more use of DirectX for the graphic design of the desktop, where they previously used GDI / GDI + API calls. What I read and was delighted by is the google translated version below: You can read the original article by Patrick here (if you know Dutch!): Unfortunately (if you aren’t Dutch) it is written in Dutch so I had to pop it through google translate (which did an amazing job). In particular it’s a good read because it contains really specific detailed information on the configuration and bandwidth levels achieved per session (<30kbps). I was delighted to read a detailed review by a Dutch consultant ( Patrick Kaak) who has been using this at a real customer deployment. During its development and various private and public tech previews this feature has been known as Project Snowball/Thinwire Plus/Thinwire+/Enhanced Compatibility mode but in the documentation it is now “Thinwire Compatibility Mode” ( read the documentation – here). My colleague, Muhammad, blogged a few weeks ago about a new optimised graphics mode that seems to be delighting users with significant ICA protocol innovations, particularly those users with constrained bandwidth ( read the details – here).
