Subject: [gentoo-amd64] MAKEOPTS values for Athlon 64 X2
Date: Mon, 15 Jan 2007 00:42:41 -0500	[thread overview]
Message-ID: <45AB1451.9010005@paulscrap.com> (raw)

Hey folks,

	I'm wondering if anyone has experimented with different values for 
MAKEOPTS="-jx" on Athlon 64 X2's.  The guides usually suggest # of 
cores/processors plus one. Looking at "man make.conf" doesn't help much, 
it just says "Suggested settings are between CPUs+1 and  2*CPUs+1". The 
only thing "man make" mentions about  the "-j" option is "If the -j 
option is given without an argument, make  will  not limit the number of 
jobs that can run simultaneously." I've also seen some mentions of -j9 
by people with dual core systems elsewhere, indicating it drastically 
speed up some emerges.

	So this leaves me with several possibilities. There's -j3 (current 
setting), -j5, -j (no limit), -j9, or some other random number. Any 
suggestions/warnings/links would be appreciated.

Thanks,
	PaulNM
