Subject [jira] [Commented] (OPENEJB-1955) TomEE 1.5.1 SNAPSHOT running slow on my production server; may be caused by Atmosphere
Date Sun, 25 Nov 2012 20:58:58 GMT


Howard W. Smith, Jr. commented on OPENEJB-1955:

pf_OrdersController is 'huge' in size (or byte count, lines of code). That is the core of
the web application. I couldn't even find pf_OrdersController in jvisualvm output; I'm glad
you found it. Evidently, I was looking at the output incorrectly.

I just navigated through some of the pages. I guess it is best to do one jvisualvm output
file per page in JSF web app.

Along with what Mark recommended about rendered=, i need to eliminate/minimize use of rendered=...
and I need to move much of the (potentially-stateless) code in pf_OrdersController to @CDI
RequestScoped or @Stateless.

So, PrimeFaces Push (Atmosphere) is not the cause of this problem? FYI, PrimeFaces Push (Atmosphere)
is working perfectly/flawlessly in TomEE/Windows Server 2003 environment; it pushes. You think
it is injection of pf_OrdersController?

> I was working with Romain and Mark Struberg on this one, and decided to open an issue,
so I could attach files and continue discussion here.
> My JSF web application is running really slow on production server (Windows Server 2003
32-bit Verizon Wireless 4G internet connection); runs faster on Windows Server 2008 64bit
(cablemodem internet connection).
> Per Romain and Mark, I ran jvisualvm, and it appears as though Atmosphere 'may' be slowing
down the web app, or the root cause.
> Please review attached files and confirm and advise.
