JRuby trunk == better/faster Rails performance

Posted on 11/03/2007, 9:56 pm, by aaron, under All.

So I remember a couple months ago playing with JRuby, and while fibonacci was super fast, Rails was way off.. ActiveRecord performance 6x-10x slower than MRI…

Looks like its getting better. Disclaimer: These are really really simple non-scientific tests.

Local mysql database, MYISAM, table people, with 2 columns, (id, name). 100k rows

> jruby -J-server -O script/console production
>> Benchmark.measure {10000.times {Person.find :first}}.total
=> 2.286
> ./script/console production
>>  Benchmark.measure {10000.times {Person.find :first}}.total
=> 1.7
Mongrel
> ab -n 1000 http://localhost:3001/people/1
Requests per second:    95.02 [#/sec] (mean)

On Glassfish v3 with: RAILS_ENV=production jruby -J-server -O -S glassfish_rails glass2, after a bit of warmup.

> ab -n 1000 http://localhost:8080/glass2/people/1
Requests per second:    48.25 [#/sec] (mean)

turning logging mostly off

> ab -n 1000 http://localhost:8080/glass2/people/1
Requests per second:    56.70 [#/sec] (mean)

All in all, thats impressive. Congrats to Charles, Ola, and the whole JRuby crew. I dont think i’ll be putting this in production yet, but I’m very interested to hear from others that have.

    Re-used your benchmarks, JRuby 1.1.1 is speeding things up, Rails perf is still in need of some attention. I know the topic is important to those who work on the project.
