Very slow initialization of Captcha

[toby451]

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

*****17 seconds****

00:01:30,292 INFO [Contexts] starting up: org.jboss.seam.ui.resource.webResource
00:01:30,293 INFO [Initialization] done initializing Seam

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!

[pmuir]

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