Perl 5.16.0 installed
I thought I would see how long my new 8 core box would take to compile 5.16.0.
It took about 18 minutes 25 seconds if stat on the build log is accurate.
So now I have the new shiny...just need to reload all the CPAN modules I use now.
Huzzah!
I blog about Perl.
Perhaps you can compare with how long it takes to compile the newest Rakudo Star, Ruby 1.9.3, and Python 3.2.3 :)
It takes my 8 core box about 3 minutes. Perl supports parallel building, but you have to enable it explicitly (perlbrew -j8)
Leon, I did -j9 for my 8 core box (can't recall if it's 4 core and hyperthreads the other 4 or is really 8 cores).
I didn't turn off testing so that probably slowed things down. That 18 minutes is for the entire perlbrew install -j9 perl-5.16.0 process.
I don't seem any time stamps in the build log.
Maybe if I get some free time this afternoon. :-)
I suppose I could do it again and turn off testing and see if I get Leon's time.
I can't imagine why you'd have an old perlbrew, but just in case -- parallel testing was added in 0.18.
Going into ~/perl5/perlbrew/dists, untarring perl-5.16.0 and going into that directory:
2 processor Core2 6400:
38s sh ./Configure -des
2m 14s make -j3
6m 2s TEST_JOBS=3 make test_harness
8 processor i920 (4+4 hyperthreads):
35s sh ./Configure -des
38s make -j9
1m 54s TEST_JOBS=9 make test_harness
12 processor 3930K (6+6 hyperthreads):
31s sh ./Configure -des
23s make -j13
1m 24s TEST_JOBS=13 make test_harness
On the 8 processor i920, with the 5.16.0 tar.gz already in place, doing 'time perlbrew install -j9 perl-5.16.0' took 3m 25s. The build log shows it running all the tests.
