We recently updated the Branch Repeater specification sheet at:
Note the addition of a Maximum HDX Sessions specification. While HDX is already optimized for a WAN, there are several additional benefits by accelerating ICA with Repeater and Branch Repeater. The Maximum HDX Sessions specification is a good rule of thumb when designing your HDX WAN deployments where WAN optimization is indicated. The specification is designed to meet a generic XenDesktop or XenApp deployment. Data intensive applications like CAD, continuous tickertapes, etc. may cause a Branch Repeater platform to hit maximum capacity before reaching the published specification.
