------------------------------------
Remy, sometimes I think that you assume that everyone is just stupid! I'm not trying
to disable keep alive. The default, unless its changed, is that for every 100 requests
the server will close the connection, regardless of the fact that the client is using keep
alive. I want to set this value to unlimited (-1), because it gives the best throughput
on benchmarks, because it never closes the connection on the server, forcing the load
driver to have to reconnect. In a benchmarking situation, you don't want that. In a
real-life application scenario, closing the connection after 100 requests may actually
make a lot of sense, but a load driver client is going to do a lot more than 100 requests.
So, yes, exposing it as an attribute does allow people to disable keep alive, which is
bad, but the default doesn't work for benchmarking. Also, I document this in the
performance tuning guide for EAP, so for customers we have good documentation that would
tell them not to disable i!

Add missing attribute to the JBoss Web XML Schema
-------------------------------------------------
Key: AS7-2096
URL:
https://issues.jboss.org/browse/AS7-2096
Project: Application Server 7
Issue Type: Task
Components: Web
Affects Versions: 7.1.0.Alpha1
Reporter: Andrig Miller
Assignee: Remy Maucherat
Fix For: 7.1.0.CR1
I have been reviewing all the XML schemas for all the subsystems, for my performance
tuning work. In looking at the JBoss web schema, there is one attribute that I would like
added to the schema so I can set its value.
You used to be able to set maxKeepAliveRequests in the old server.xml, and I would like a
corresponding element added to the new AS 7.x schema. This particular attribute has been
key in getting the maximum throughput on various workloads.
