1. Does anyone know the definitive difference between real, usr, and sys time? (I am currently researching this, and will add it if I figure it out.)

2. Wouldn't either *nix or Unix-like be more correct than Unix?

IIRC, real means wall clock time (i.e. real-world time), usr is user-space or regular program time (whether cycles or real time I'm not sure), and sys is, I believe, time spent on system calls and the like. Don't take my word for it, though, I'm not entirely certain of that (I usually only care for the real measure, see). As for *n?x, yeah, that might be more accurate since Linux and others probably copy it, but I don't know if there are any variances to those. -- Keilaron (talk) 15:03, 15 December 2007 (UTC)
