XenApp 1912 (CU1) Using auf very slow and laggy when using HDX with EDT/UDP

Robert Kuehne


We have set up an new installed Xenapp Farm with XA 1912 CU1 on Server 2016. The most of our clients are HP and IGEL Thinclients When we have  HDX over UDP/EDT enabled, the Performace seems very slow, poor and laggy e.g. Stuttering Scrollbars in Word, Excel and such things. Now we have disabled UDP Complete and use TCP , all works fine.  I have found this Problem in other Topics but no solution.


Has Anyone Fix it or found a reason ?


Does the HDX/TCP Setting have an impact on use of the Realtime Audio Setting ?


best regards
