Benchmarks In continuing with my articles exploring the my SPARC-based Sun Ultra 5, I'm going to cover the topic of compiler optimizations on the SPARC platform. While many are familiar with GCC compiler optimizations for the x86 platform, there are naturally differences for GCC on SPARC, and some platform-specific issues to keep in mind.

Where's the -Os flag?

Too bad that you didn't test the -Os flag. When the file is size-optimised, then the possibility of the L1 and L2 cache hit would be bigger and this makes it faster too.
