I can check this. I have been benchmarking the Intel compiler suite vs. the GCC suite on the Itanium and I am seeing a very unofficial 40% improvement using the Intel suite over GCC. I copied myself on this and I'll try to answer this on Monday. They certainly have more sophisticated profiling. Another member of my team is doing some work on profiling.
However, there are some tools that use counters on chips and in the OS to provide additional information.
I roger that on the speed-ups, I have seen *VERY* impressive speed-ups w/ the Intel Compilers ....
