Taken from
http://lists.opensuse.org/opensuse-factory/2006-10/msg00173.html

  We run SPECcpu2000 benchmarks on x86-64 to compare -Os and -O2. The
  results are 1011 (-Os) and 1140 (-O2) for SPECint and for a subset of
  SPECfp 1202 (-Os) vs. 1270 (-O2), so the speed difference is too high
  to make this change.
 
  Overall .text size of all benchmarks:
  6038603 (-Os) vs 6816414 (-O2)
 
  With filesize begin nearly exactly 1MB larger in both cases.
 
  We'll stay with -O2.
