Why Rails app on glassfishv3 much slower than on webrick, any suggestions?

Thank you your suggestion, I tried glassfish gem deployment, it works as well as webrick.

However, the performance problem of jruby + glassfish v3 seems still there. As you mentioned, this may be not caused by glassfishv3. Finally, I find this problem may lie in ActionRecord.

I did the following test:
Application environment:
Server: WEBrick1.3.1
Database: Oracle 11g
Ruby version 1.8.7 (java)
RubyGems version 1.3.5
Rack version 1.0
Rails version 2.3.4
Active Record version 2.3.4
Active Resource version 2.3.4
Action Mailer version 2.3.4
Active Support version 2.3.4
Environment development
Database adapter oracle_enhanced


Controller:

class TestSessionController < ApplicationController
def index
puts Time.now.strftime(some format)
@blog=Blog.new
puts Time.now.strftime(some format)
end
end

After run the application on WEBrick,the console outputs the following information:

2010-01-12 14:52:50.531000 +0800
2010-01-12 14:52:50.953000 +0800

Now I change the server to glassfish v3, I get the following information:

The execute time of glassfish is much longer than Webrick, I am really curious why there is such a big difference in executing only a simple line of code? [b][/b]
