Floating Point Benchmark: Ruby Language Updated
I originally posted the results from a Ruby language version of my floating point benchmark on 2005-10-18. At that time, the current release of Ruby was version 1.8.3, and it performed toward the lower end of interpreted languages: at 26.1 times slower than C, slower than Python and Perl. In the twelve years since that posting, subsequent releases of Ruby have claimed substantial performance improvements, so I decided to re-run the test with the current stable version, 2.4.2p198, which I built from source code on my x86_64-linux development machine, as its Xubuntu distribution provides the older 2.3.1p112 release. Performance has, indeed, dramatically improved. I ran the benchmark for 21,215,057 iterations with a mean run time of 296.722 seconds for five runs, with a time per iteration of 13.9864 microseconds. The C benchmark on the same machine, built with GCC 5.4.0, runs at 1.7858 microseconds per iteration, so the current version of Ruby is now 7.832 times slower than C, making it one of the faster interpreted or byte coded languages. I have updated the language comparison result table in the FBENCH Web page to reflect these results. Here is the table as updated. I have also updated the Ruby version of the benchmark included in the archive to fix two warnings issued when the program was run with the -W2 option.| Language | Relative Time |
