Subject [jira] Commented: (GERONIMO-5668) Use fewer acceptor threads for Jetty
Date Mon, 08 Nov 2010 10:15:11 GMT

    [ https://issues.apache.org/jira/browse/GERONIMO-5668?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12929534#action_12929534

Shawn Jiang commented on GERONIMO-5668:
---------------------------------------

Thanks Trygve,

With other fix 2.2@1031437, 2.2 TCK passed with  jetty(7.2.0.v20101020) build.   I think we
are safe to release 2.2.1 without another jetty release.

Sure it's better to include the new jetty release with the fix to the root cause if possible.

> Geronimo applies the maxThreads parameter as the number of acceptor threads in Jetty,
with a default value of 50. With newer versions (7.2.0) of Jetty this gives the following
warning during startup:
> # Acceptors should be <=2*availableProcessors
> Server shutdowns are also very slow, it takes about 1 second to stop each acceptor thread.
> The attached patch sets the number of acceptor threads to 2 per connector (HTTP, HTTPS
and AJP), and exposes this and the acceptor queue size (50) as a parameter in config-substitutions.properties.
