Subject Re: Coyote/Http11 under load
Date Fri, 08 Nov 2002 06:53:27 GMT
My patches to o.a.c.tomcat3 shouldn't do anything to turn TC3.3+Coyote from
a dog to a cat ;).  They are just clean-ups.

Keith seems to have narrowed it down to o.a.c.tomcat3 (since o.a.c.http11 is
shared with Tomcat 4, and the rest of 3.3 is shared with the
Http10Connector).  However, I can't find anything there just by looking
(and, this is one of the thinnest packages you can find).  The
CoyoteConnector add a preService method (which has a similar method in 4.x),
and a postRequest method (which is presumably for Jk2, since it does nothing
for HTTP).

I'm not going to have time for probably at least a couple of weeks to be
able to run 3.3.2-dev under OptimizeIt to try and pin down where the bottle
neck is.  But if someone else has time, I can try and answer the "why does
this do that" type of questions.
