Don't give up on compiler options!  I would happily accept a patch that 
changed compiler optimization options, especially if there were 
benchmark results to demonstrate the benefits.

Keep in mind though that we have to support many different processor and 
OS combinations.  Steve may have more recent stats on what chips our 
users are actually using, but I would be a little nervous, for example, 
deciding to drop support for PIII chips without a solid benchmark.  We 
don't really want to be doing multiple Windows builds internally.

I would be curious about benchmarks where SSE code generation was turned 
on for all files.
