You don't mention RGS but you do mention sender and receiver so I am guessing your performance issue is with using RGS. What version of RGS are you using? What are you doing when you are seeing performance issues, and what exactly are you referring to as far as performance. If viewing video, you could enable AVC, and see if that helps. Also try HP Velocity. There are performance settings within RGS, but without knowing the version of RGS you are using would hesitate to provide direction.
