Hi,

I recently installed AMD64 6.2 Release on 2 PowerEdge servers, both with
dual core Xeon (3070 and 5110).
I extensively benchmarked different compiler options on Xeon 5160 (3.0
GHz Core2) with gcc-4.1.2 and gcc-4.2.

Using what benchmark? That makes a *lot* of difference.

A proprietory application. I should have mentioned it does almost no
floating point, so the assumption to drop sse might not be valid.

However, the differences in compiler flags were generally huge and and
the simpler ones came out on or near the top.
