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 the different operations of ActionRecord.<o:p></o:p>
I did the following test:
 Application environment: <o:p></o:p>
Server: WEBrick1.3.1
Database: Oracle 11g
Ruby version 1.8.7 (java)<o:p></o:p>
RubyGems version 1.3.5 <o:p></o:p>
Rack version 1.0 <o:p></o:p>
Rails version 2.3.4 <o:p></o:p>
Active Record version 2.3.4 <o:p></o:p>
Active Resource version 2.3.4 <o:p></o:p>
Action Mailer version 2.3.4 <o:p></o:p>
Active Support version 2.3.4 <o:p></o:p>
Application root C:/Documents and Settings/Administrator/My Documents/NetBeansProjects/RailsApplication1 <o:p></o:p>
Environment development <o:p></o:p>
Database adapter oracle_enhanced <o:p></o:p>
Database schema version 2010011005140
<o:p></o:p>
View: <o:p></o:p>
TestSession#index<o:p></o:p>
Find me in app/views/test_session/index.html.erb
 <o:p></o:p>
 Controller:
class TestSessionController < ApplicationController

  def index
    puts Time.now.strftime("%Y/%m/%d %H:%M:%S.#{Time.now.usec} %z")
    @blog=Blog.new
    puts Time.now.strftime("%Y/%m/%d %H:%M:%S.#{Time.now.usec} %z")
  end
end

 
Model:
class Blog < ActiveRecord::Base
end
After run the application on WEBrick and access the controller with http://localhost:3000/test_session, the console outputs the following information:
 2010/01/12 14:52:50.531000 +0800 
2010/01/12 14:52:50.953000 +0800 <o:p></o:p>
Now I change the server to glassfish v3, and access the controller with http://localhost/RailsApplication1/test_session, I get the following information: <o:p></o:p>
<o:p>Information: Processing TestSessionController#index (for 127.0.0.1 at 2010-01-12 15:00:31) [GET]

 and table_name = 'BLOGS'
 order by column_id

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?<o:p></o:p>
