If you havent already, I would first verify that its actually CPU bound, |
2 |
before changing CFLAGs and recompiling everything. So take a look at top, |
3 |
vmstat, mpstat etc when you're noticing slowness. If it is truely CPU bound |
4 |
and you're going to recompile everything, you could consider upgrading to |
5 |
the ~ version of gcc first, with the assumption that the optimizations |
6 |
maybe be better. However, my gut feeling is that you wont get much or any |
7 |
improvement over your current CFLAGs. |

The i686 and -Os ideas are interesting. See if you can find any benchmarks. |

Also - try diffing the kernel .configs - maybe you missed something |
12 |
important on the slow system. |
