From: Dan Connelly Date: 2012-07-03T09:06:50+09:00 Subject: Re: ruby performance I should provide version numbers... the RHEL on work machines is pretty backwards. Ruby: 1.8.1 Perl: 5.8.8 I ran on my personal Macbook Air with Ruby 1.9.3 and Perl 5.10, and Perl was only 2x faster. So it seems Ruby 1.9 is indeed substantially faster (assuming Perl is fairly stable). Curious when I did the loop in C how huge the speed increase was with -O1 versus -O0... #include int main(void) { int i = 0; while (++i < 10000000); printf("i = %d", i); return 0; } but that's a bit off-topic... -- Posted via http://www.ruby-forum.com/.
