I've been doing some googling, and what not, came across the stage 1/3 install, stage 1 directions, etc... and read and read and read (from my current knoppix install). Anyways, I've basically been planning to upgrade from an IDE drive to a SATA (software) RAID 0 drive and figured this was a good time to try a stage 1 install. After reading through some of the docs I've found though, it seems to me like the only difference between a stage 1 and a stage 3 is some lack of optimization on the base system in stage 3 (which could be optimized by just forcing the system profile to be rebuilt 2x; once for buiulding the updates, a second time to build the optimized and updated binaries from the optimized, and updated, binaries).

I'm (sort of) new to gentoo, but been a debian user for years, so I know my nix enough to fight through the occational error, or build a custom kernel. Running a P4 (undercloaked at 2.8Ghz) with duel channel 2x512MB RAM, SATA 1 2x320GB HD.

Anyways if this mumble didn't make much sence (I have that special supervillen ability), the question goes:

1) Stage 1 vs Stage 3; whats better for perfomance? Whats the cause of the difference (ie: no optimization of gcc? libc?)?

2) Stage 3 after a complete (tiny, ie: no X, mail, etc...) install, doing a rebuild of all installed apps (including gcc); is this == to stage 1 install? why is it or why is it not?

I'm looking for reasons here, not just stats, or feelings, or opinions. Also install time is not an issue, main concirners are stability, (HD) space, and speed.

A touch off topic, I'm thinking these flags in make.conf:

CHOST="i686-pc-linux-gnu"
CFLAGS="-march=pentium4 -O3 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"

They seem to be well tested/stable for the P4 and give good speed/size (of resulting binary) results.

Thanks in advance :D Hope to hear some interesting replies ;)

The official line is that stage3 is supported and stage1 is not. As for pros and cons to each, search the forums (use google) as there have been an absurd number of threads on this topic.

Moved from Installing Gentoo to Duplicate Threads, please see this topic: What exactly happened to stage 1? And bootstrapping?
