Is discovery studio compiled with intel or amd compilers or both?  We are currently running DS on a dell with 4 Intel Xeon 5160 cores.  We are thinking of moving it to a machine with 24 amd istanbul cores.  Which machine should have the best individual core performance?  Obviously 24 cores will give us more throughput but in other applications we have that are optimzed with intel compilers, the istanbul cores are actually 25 to 50% slower than the 3 year old xeons.
