What kind of performance improvement will I see from Sun Studio 10 compilers?
It will generally vary by the kind of application you have and what hotspots it can present to the compiler to optimize. With SPEC, we expect to see 10% improvement in SPEC INT and about 40% in SPEC FP. Taking advantage of AMD64 hardware, instructions and memory model, can yield 7-20% improvement over 32-bit applications. With the improvements we have added to Sun Studio 10, you might see significant improvements above that threshold. To be fair, the compiler will be in a constant state of improvement up until final release of Sun Studio 10, so exact numbers would be hard to give.
