I have a PPro 166 with 512k cache, 32M FP RAM, 2G Barracuda, 2940. "make world" for 2.2.2 (recent cvsup) takes 2:47. Mounting /usr with "-o async" drops that time to 2:15. It was interesting to note "time" reported almost exactly the same amount of time in CPU for both. dg@root.com said: > >CFLAGS= -O2 -m486 -pipe > Make that "-O" and kill the -m486.

I remember my old MB could "make world" in 5 hours or so once, and was up to 9 hours by the time I replaced it. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
