Hi.
Just installed a new DL360 with 8 cores at 2.33 Ghz and 8 GB ram and
15K rpm sas-disks. When I installed the beta2 from cd 'make -j 9
buildworld' took approx. 20 min. After a recompile of userland and
kernel and switch to ULE it went down to:
World build completed on Wed Nov 14 17:44:08 CET 2007
--------------------------------------------------------------
3552.428u 1298.485s 16:15.89 497.0% 6156+1325k 25257+8117io 3368pf+0w
Not very scientific and only one run but none the less my fastest
buildworld time ever on FreeBSD. :-)
Congrats! :-) 16 minutes is really impressive...
Our 2.13GHz C2D 6420 boxes w/ 2GB RAM can do this in about 19 minutes
flat (using ULE scheduler). Disks are 7200rpm SATA300. make -j2 used;
and this was RELENG_6.
The reason I like the buildworld "benchmark" is because it's a fairly
real-world test and not something specific to just one piece of how
a machine behaves (e.g. memory benchmark, disk benchmark, CPU benchmark,
etc.).
It's not a good SMP benchmark though, because large parts are entirely
single-threaded, and other large parts do not parallelize beyond more
than a couple of CPUs. Also it is entirely incomparable between
different versions of the source tree.
