So I cannot reproduce the slow down to 4-5MB/s on the same VM I was able

Yes. Although the original version of the file was 20 seconds.

I have a commercial app running Tomcat 6. I don't really know anything
about Tomcat, so I need some help with performance tuning.
What happens is that a small percentage of connections from our client
machines just timeout on the connect. I assume I'm running into some
limitation in Tomcat.

I'm not sure that this is a good strategy for Tomcat installations.
Some distro's are very slow about updating their packages.

It makes sense.
This tomcat 5.5 is a tarball from Apache. Do you suggest using a rpm (I'm

Apache?

Miguel,
just a couple of general remarks.
Tomcat is an open-source project, developed and supported by volunteers.
These volunteers do not have all the time in the world, so they tend to focus first on the

Look at Connector.setProperty(name, value).
That method is what should be called by digester that parses the XML file.

I've spent few days trying to figure out what's going on but I give up.
I've tried boosting max_packet_size and few other properties but with no
success.
