Hi Mark,
On the slowness, this is when they are retrieving random .js files from the
exploded war file after deployment. It's taking an a long
amount of time. Some of these are quite large, like 2MB or more. When the
issue shows, doing a curl we get to here and then it pauses for some time
before it feeds back the data.

And it just hangs out here before finally getting the requested file.
In looking at the catalina.out log file, I am not seeing any
errors/stack-traces.
Any ideas as to what may be causing this?
Thank you,
