Is there a good reason to use -O3 rather than -O2? -O3 can bloat the code which can increase cache pressure, which is not always noticeable in benchmarks but hurts real-world programs. Unless benchmarks are significantly better at -O3, -O2 is a good default choice. -- Andrew Haley Java Platform Lead Engineer Red Hat UK Ltd. <https://www.redhat.com> EAC8 43EB D3EF DB98 CC77 2FAD A5CD 6035 332F A671
