Full make world takes 1:15-1.25 depending on how much I use the system in between, and oh, its running under X while doing this... So either the PII is a bunch'o'crap (which we allready know), or we are bound by other things than pure CPU & disk bandwidth :) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Søren Schmidt (sos@FreeBSD.org) FreeBSD Core Team Even more code to hack -- will it ever end ..
