Optimized programs - bang for the buck?

[liquiz]

Hello Everyone

Im about partway through a stage 3 install, actaully Im done and Im emerging in my extra packages. I have a speedy ultra 5 with a 9g hd in it.

I set up the system with the -O3 -pipe and ultrasparc gcc CFLAGS and now Im drudging through the emerge process.

The question is this:
What packages or types of package benifit the most from being recompiled with the new gcc settings?

Ultimately the system is just supposed to be a web/mysql/mail/ftp server with a side order of samba thrown in. The system is behind a work firewall so its not going to be seen by the outside world.

Peace,
Liquiz

If you have something that is going to be doing a lot of number crunching (like gcc or sendmail) rebuild it ...

on a system like an U5 the differance may only be in seconds/minuts but on larger systems it can be significant .. its a good habit to optimise yoru stuff when you have the oppertunity.

I use a U1 170 for web/mail/dns and had average 45% load, but after some compiler flag tweaking and recompiling (same versions) got it down to about 30%

I hadnt thought about gcc being cpu intensive but your right.

I went for the following first

bzip2
gzip
tar
gcc
sshd

That was enough to get the system up and running and so far things have been "Stable?"
