It's got a single RM7000 CPU @ 350MHz, with 256KB L2, 1MB L3 and 1GB RAM. About as maxed out as this machine can get in Linux. So, no, not fast, especially for compiling code, but such is the way in Gentoo. I'm actually re-installing it with a uClibc-based filesystem, as glibc-linked binaries/libs shuffle too large of code around and this thing's memory subsystem is rather slow. For reference, anyone whose read the "UserFriendly" comic series, Erwin is an SGI O2 machine. -- Joshua Kinard Gentoo/MIPS kumba@xxxxxxxxxx 6144R/F5C6C943 2015-04-27 177C 1972 1FB8 F254 BAD0 3E72 5C63 F4E3 F5C6 C943 "The past tempts us, the present confuses us, the future frightens us.
