MongoDB and MySQL in Ruby and PHP

Some time ago I became quite interested in developing for MongoDB and held some benchmarks in comparison with MySQL.
Initially only in Ruby, but when the results were astonished (for the worse), then in PHP, for comparison.
Maybe it will save someone some time.

Initial data:

• System: $ uname -a<br/>Linux pavlin.ik 2.6.31-gentoo-r4 #1 SMP Sun Nov 1 18:21:31 MSK 2009 i686 Intel(R) Core(TM)2 Duo CPU T5450 @ 1.66GHz GenuineIntel GNU/Linux
• MongoDB v. 1.0.1
• Gems:
  • gem mongo (0.16)
  • gem mongo_ext (0.16)
  • gem mysql (2.8.1)
  Ruby:
  • ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-linux]
  • ruby 1.9.1p243 (2009-07-16 revision 24175) [i686-linux]
  • ruby-enterprise-1.8.7-2009.10
  PHP 5.2.11-pl0-gentoo with Suhosin-Patch 0.9.7 (cli)

The source code of the tests is here: http://github.com/latrommi/benchmarking

Actually, the results:

There is only one conclusion: it does not mean that MongoDB is worse than MySQL, it means that a normal, fast Ruby driver is not written for it :)

PS will be cool if someone conducts similar tests for Python.
PPS take this opportunity to say hello to TravisBickle ;)
