Ive installed a new virtual 2012 R2 server into an existing environment where they were using 2003 terminal services. Im having massive problems with performance on it, the 2003 environment on the same server runs fine with the same load but when they log into the 2012 box the processor jumps up to 90-100% at times and everything runs super slow. They only run an in house app which lives on a seperate box, outlook 2010 and internet explorer..
This is on a Dell T420 with a raid 10 setup on a battery backed raid card, dual xeon processors, 32Gb ram. And also none of the other virtual servers on the system are ever sluggish.
Anyone had this type of issue with 2012 R2 RDS?
