Subject [jira] Updated: (GERONIMO-5668) Use fewer acceptor threads for Jetty
Date Wed, 17 Nov 2010 11:37:13 GMT

     [ https://issues.apache.org/jira/browse/GERONIMO-5668?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Trygve Sanne Hardersen updated GERONIMO-5668:
---------------------------------------------

    Attachment: geronimo-2.2-1035896-jetty-7.2.1.patch

Thanks for testing Shawn. Jetty 7.2.1.v20101111 has been released to the central Maven repo.
I'm attaching an updated patch against Geronimo 2.2 r1035896. The comments in the patch are
there to explain my thinking - feel free to remove them.

Thanks!

> 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.
