This is a test of the difference in port building speed with and without FORCE_MAKE_JOBS in /etc/make.conf. There is a whole lot of ports installed on this machine (X + applications like Firefox and OpenOffice):
[tykling@tyklappy ~]$ pkg_info | wc -l
440
The machine is a Lenovo X301 with a solid-state disk and the following CPU and RAM:
[tykling@tyklappy ~]$ grep "l memory" /var/run/dmesg.boot real memory = 6442450944 (6144 MB) avail memory = 6066290688 (5785 MB)
[tykling@tyklappy ~]$ grep CPU: /var/run/dmesg.boot CPU: Intel(R) Core(TM)2 Duo CPU U9600 @ 1.60GHz (1602.39-MHz K8-class CPU)
The machine is configured with ZFS and is running great with X, everything seems to work. I've posted a dmesg [here].
Testing
This is the command I run to rebuild all ports (except for portmaster):
portmaster --no-confirm -afB -x portmaster
Test 1
First test is a build with the default settings.
/etc/make.conf:
# added by use.perl 2010-04-13 22:07:18 PERL_VERSION=5.8.9
Resultat:
real 378m53.008s user 403m40.086s sys 99m14.101s
Test 2
Second test is with FORCE_MAKE_JOBS enabled - MAKE_JOBS_NUMBER is set to 2 in this test, which would have been the default if I had not set MAKE_JOBS_NUMBER since there is two cores in the machine I am running this on.
/etc/make.conf:
FORCE_MAKE_JOBS=YES MAKE_JOBS_NUMBER=2 # added by use.perl 2010-04-17 03:07:25 PERL_VERSION=5.8.9
Resultat:
real 343m5.886s user 405m43.557s sys 98m56.720s
Test 3
Third test is with FORCE_MAKE_JOBS enabled - MAKE_JOBS_NUMBER is set to 4 in this test, double the number of cores in the machine.
/etc/make.conf:
FORCE_MAKE_JOBS=YES MAKE_JOBS_NUMBER=4 # added by use.perl 2010-04-17 03:07:25 PERL_VERSION=5.8.9
Resultat:
real 339m
(From memory, I don't have the rest of it)
Conclusion
From 378 minutes to 343 minutes, or 35 minutes saved. Not bad.
