So far I've been using same as above, with the addition of |
11 |
-momit-leaf-frame-pointer (which likely doesn't matter nearly as much |
12 |
on amd64 than x86 due to less register pressure, but can't cause too |
13 |
much damage (I generally only use gdb for backtraces, most of my |
14 |
system debugging is done with strace/ltrace, so not getting precise |
15 |
debugging doesn't bother me much)). |

I may play with -mtune to see what kind of performance change I see |
18 |
with mencoder, openssl, etc with different instruction schedulings. |

lockups or scary log messages under fairly heavy CPU and disk load. |
