I think what we are looking for is here :

http://tomcat.apache.org/tomcat-7.0-doc/config/http.html#NIO_specific_configuration

useComet (bool)Whether to allow comet servlets or not. Default value is true.

I set connetor attribute to false useComet to false,but did not work as I 
expected,

still created those :

In http://tomcat.apache.org/tomcat-7.0-doc/config/http.html
you can read about pollerThreadCount and useComet flags for the APR 
implementation.
You don't need Comet unless you applications specifically are using it, most 
likely they are not.

Poller & CometPoller general questions

2012-07-13 Thread Jeffrey Janner 
I'm more curious here than there being a problem.
Are the Poller & CometPoller threads necessary for Tomcat operation?  If not, 
how to turn them off, and do I want to turn them off.
Here's my scenario:
Tomcat 6.0.33 with APR on Windows Server 2008 (regular and R2).
Fairly normal server.xml, with generic  implementation, i.e., not 
explicitly specifying the protocol:
  
  


Web.xml is set up to force everything to HTTPS:

  CONFIDENTIAL


So Tomcat starts up and creates, in my case, 32 poller threads, 8 poller and 8 
cometpoller for each connector.
Now, I know these just sit around waiting on AprEndpoint$Poller, basically 
doing nothing and really causing no harm, other than taking up some threads out 
of my available threadpool.
I pretty sure we don't use Comet, so I'd like to turn those off, but it's not 
clear in the documentation that I can, only looks like there are controls for 
the NIO connector.
What, if anything, would the standard Poller threads be used for?
Since everything gets forwarded to HTTPS, the HTTP poller threads seam 
exceptionally useless.
