    Very slow initialization of Captcha

    Tobias Hill Newbie

      When redeploying a Seam application the initialization of Captcha takes a
      very long time. On my system (New Lenovo T60 + Vista) it is hanging
      for more than 50 seconds at each redeploy.

      Example from my logs:
      09:09:50,311 INFO [Contexts] starting up: org.jboss.seam.captcha.captchaImage
      09:10:44,093 INFO [Initialization] done initializing Seam


      Any way to make this startup quicker? Currently those 50 seconds
      are harming productivity.

      Thankful for any suggestions,
      Tobias

          I've got a Lenovo Z61p (similar specs to the T60) and it takes nowhere near that long on my machine:

          01:44:20,781 INFO [Contexts] starting up: org.jboss.seam.captcha.captchaImage
          01:44:21,718 INFO [Initialization] done initializing Seam


          Which JVM version are you running? I'm using Sun JDK 1.5.0_11.

            Shane thanks for taking your time.

            Strange that it differs so much. I was using 1.5.0_12. Changing to 1.5.0_11 does not change it much:

            10:51:37,795 INFO [Contexts] starting up: org.jboss.seam.captcha.captchaImage
            10:52:18,156 INFO [Initialization] done initializing Seam
            


            Moreover I am using JBoss-4.2.1.GA. On Vista as I mentioned.

            Same application deployed on Ubuntu Linux on JDK 1.5.0_11 initializes captchaImage in 2 sec.

              Unless you have done some timings you aren't mentioning I suspect its actually delaying on something other that captcha creation. Have you looked at the server.log for debug messages?

                Hi Peter & Shane,

                As can be seen below it seems that HeirarchicalLoaderRepository3 is slow at two points during Captcha init.

                I am still clueless on this one bu will continue to investigate. Any insightful points will be much appreciated.

                Cheers,
                Tobias

                  Ok solved it ...

                  Avast! antivirus + Vista => Captcha initializes in 1 min :-#
                  Avast! antivirus + XP => Captcha initializes in 2 s :-|
                  Avast! antivirus disabled + Vista or XP => Captcha initializes in 1 s :)

                    I'm on a Mac without antivirus. I've just added Captcha to one of my projects and I now see a 17 second pause during startup that was not there before. This is out of 39 second total start time, so it's a significant pause.

                    00:01:13,660 INFO [Contexts] starting up: org.jboss.seam.captcha.captchaImage

                    My machine is very fast with tons of ram, no anti-virus, running the latest 1.5 jvm for the mac: 1.5.0_07-87

                    Any ideas?

                    Thanks in advance!

                      I don't see any problems with starting captcha on a mac, same jvm. Post the debug log for that period
