I'm using Lync 2010 server to handle some clients communication and screen sharing. The biggest issue is the performance with screen sharing, it is of rather high quality but the frame rate is very poor.

I have been reading and searching a lot on the subject and 95% of all topics is about bandwidth, we have a 200/200 MBit Internet connection solely for this application. Also my test machines runs on an internal gigabit lan. The speeds between all boxes is hysterically fast.

Next step was to ensure that there where some profiles for different bandwidths, so i registered some

New-CsNetworkBandwidthPolicyProfile -Identity 50Mb_Link -Description "BW profile for 50Mb links" -AudioBWLimit 20000 -AudioBWSessionLimit 200 -VideoBWLimit 14000 -VideoBWSessionLimit 700

New-CsNetworkBandwidthPolicyProfile -Identity 100Mb_Link -Description "BW profile for 100Mb links" -AudioBWLimit 30000 -AudioBWSessionLimit 300 -VideoBWLimit 25000 -VideoBWSessionLimit 1500

Nothing fancy happend here either.

Non of the test boxes have anything from Norton installed, they doesn't have any firewalls running (nor does the Lync server), all fences are down in this environment just for the testing.

Is there any thing that I may have missed to improve the quality of this?

Thanks
