We have two identical servers with the following specs:
- 4 sockets containing AMD Opteron 6172 at 2.10 GHz each of which have 12 cores
- 64 GB RAM
One runs Windows Server 2008 R2 Standard, which therefore can use 48 cores and 32 GB RAM.
The other runs Windows 7 Professional, which therefore can use 24 cores and 64 GB RAM.
I ran a single threaded performance benchmark and the Windows Server machine was 1.5 times slower.
Any there any suggestions as to how I can find out why Windows Server is so slow?

Soudns broken. I would stop using single threaded applications at that point and pull out a standard perforamnce test.
There is nothing in windows server that makes it slower by a large degree. Not sure what difference you saw - a "factor of 1.5" is not very clear. you mean 1 secod and 1.5 second on the server?
Pull the serers out, run cpu performance tests on both. YOu may find their performance is different. I see nothing on a stock server causing this.
