Running test Rails app under JRuby and JBoss - experiences


#1

Based on this article http://blog.saush.com/?p=208 I have created a
simple speed test application to see how JRuby behaves under JAVA
server. I created one controller with simple method that provides actual
time for view. View is RHTML with simple code for publishing the time
provided by controller.

Then a packed the application into WAR(described in article) and
published under JBoss 4.0.5 (on WinXP, 1GB RAM, Centrino Duo 1.8GHz) and
latest JRuby 1.0 . Checking using a browser I can see, the application
is running fine. Then I used ApacheBench to stress the application.

Results seems to be great.
For

ab -n 1000 -c 20 http://localhost/jrails/company/index

… I can get up to 500req/sec . Its unbelievable for me. It leads me to
think if there is any bug/problem I cant see. Can someone help to
understand or do you have some results to compare?

You are not hitting a valid page or its returning an error or
redirect, that is why its so fast, See how 981 are non 2xx responses?
This means that they either failed or just did a redirect.
