Hi,
I recently installed AMD64 6.2 Release on 2 PowerEdge servers, both with
dual core Xeon (3070 and 5110). I noticed when I was updating the
sources that it was compiling as an Athlonxp by default. I was wondering
if I should change the CPUTYPE in make.conf to something else. I read at
some places that it is not recommended because it could cause problems
but I thought it would be interesting to start the debate here. Please
note that I would prefer not to go with the -STABLE or -CURRENT branch
because these a going to be essential productions servers.
Thank you for your opinions,
Martin
I use nocona. That should be the correct one.
I know I am hijacking the thread a bit - but:
In general, how does one decide which CPUTYPE to use? The connection
between the options for CPUTYPE and the output of dmesg is not so
obvious to me. I looked at the features advertised by dmesg (which in
my case included SSE3) and then reverse engineered bsd.cpu.mk to figure
out I should be using "prescott," but I am hoping I figured it out the
hard way.
Also, does setting CPUTYPE make a lot of difference to performance?
Right now I have no CPUTYPE set at all.
Thanks, Stephen
