We were going to enable this weeks ago, but found that EDT completely destroys WebEx meetings. RTTs were over 2000 constantly during a meeting, and the audio/video was effectively useless. Could very well be our environment, but it’s worth testing if you haven’t already done so. It was the only app that we had an issue with while EDT was enabled.

I guess once you find the correct MTU size and add this sure . I just want it to work without all the extra settings. 1. NetScaler upgrade: need to upgrade NetScaler to 12.1.56 ( for MTU discovery. 2. 1912VDA, add this DWORD: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\icawd Name: MtuDiscovery Type: DWORD Data: 00000001 3. On Storefront add this default.ica, add this lines: OutBufLength=1472 udtMSS=1472 edtMSS=1472

Are you having any issues Ray?

Well I haven't set what I posted above yet, Because I have to finish upgrading the netscaler. However, Support is telling me, I have to put all above in place still. Even with MTU discovery on. So I am a bit confused why, if MTU discovery is on. I had to revert from UDP to TCP because of the session performance of the fragmentation of packet.
UDP may help but man it KILLS session performance if MTU is not correct

Currently discovery only works with Windows CWA >= 1911 I think, with VDA >= 1912. I'm using EDT remotely right now from macos to a 1912cu1 VDA, with no pMTU discovery configured yet, and it's great for what i'm doing - but ctxsession shows my MTU as 1500, so i'm probably just lucky :)
