I am building a new server to host Windows Server 2012 Terminal Server in Hyper-V sessions.  This will be an IBM x3550 with two CPUs.

We plan to host about 50 total users in two seperate VMs.

For the same amount of money, I can get 8 core CPUs with 20 MB cache running at 2.1 GHz or I can get 4 core CPUs with 10 MB cache running at 3.3 Ghz.

What is more important for terminal server, cores or speed?

That test was for VDIs.  Do we know is the same holds true for traditional terminal services sessions?

With anything that involves a large number of threads such as terminal server cores always win over clock speed because each thread (and therefore each core) spends a lot of its time waiting on I/O. For the same reason you should enable hyperthreading so it can push the thread that's waiting on I/O to one side and run another thread on that core instead.

Page 16(46) shows little difference (about 10%) between 2.0 and 3.16GHz but page 20(46) shows good scaling (70%) when doubling the number of cores.
