I'm running Rails on Linux (ubuntu 7.0.4). It turns out that when installing Ruby via apt-get, you get a generic build that hardly uses the instruction set. It recognizes your system as 'i486-linux'.
When you build Ruby from source, it builds as 'i686-linux'.
The speed improvement, for the same code is about x2 (so it's kinda worth the effort).
It works MOSTLY OK, but I've still got some critical things that will not install: - openssl - readline (so, script/console doesn't run)
Anyone did the same thing (e.g. install Ruby from source and then Rails) and got everything to work?
Thanks, Helzer
