Improved Remote Desktop Connection Broker Performance with Windows Server 2016 and Windows Server 2012 R2 Hotfix (KB3091411)

The Microsoft RDS Product team has released on important hotfix for RD Connection Broker performance running on Windows Server 2012 R2 and Windows Server 2016!

Have been waiting for this one to be released! Glad to see its now publically available!

“…Internal testing of the RD Connection Broker connection-handling code shows a significant improvement during logon storms and when adding/restarting RD Session Host servers to a farm. We also see similar improvements through internal testing of the end to end connection scenario via the Windows RD client (MSTSC).

Specific results include:

Logon Storm
- 100% connection success with initial burst of 100 connections at a rate of 2 connections per second
- 0.2 second average connection time through RD Connection Broker, down from over a minute

RDSH Add/Restart
- 100% success adding/restarting servers at rate of 1 server per second with 5 sessions per server
- 2 second average add/restart time, down from over thirty minutes

MSTSC End to End
- 100% connection success at a rate of 100 connections per minute
- 25 second average connection time, down from over seven minutes…”
