Ruby is marginally faster than PHP until you do anything with the database. If you’re using Rails forget about performance.

Of course I’ve seen many, many other benchmarks of Ruby 1.9 and 1.91 that show it as significantly slower than 1.8.6 too, so I’m not sure if this is even legit or not.

Anyone run tests with compiled PHP (Zend encoded for instance)?

That also should be considered.

I ran your code on my dev box a deb 5.0.3 (lenny) set up with stock php/ruby packages

$ php -v
PHP 5.2.6-1+lenny3 with Suhosin-Patch 0.9.6.2 (cli) (built: Apr 26 2009 22:16:23)
$ ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]

$ time ./mergesort.php

real 0m6.303s
user 0m6.200s
sys 0m0.032s
$ time ./mergesort.rb

real 0m8.043s
user 0m7.752s
sys 0m0.292s

But this one simple test is hardly enough to evaluate an entire language. These guys have been benchmarking languages for years:

php is generally faster, although ruby 1.9 does better. Jruby doesn’t impress me at all.
