Howard W. Smith, Jr. commented on OPENEJB-1955:
-----------------------------------------------
20121128_profileLogin1.jpg
Shows the performance of my original use of JPA, which includes dynamic SQL
(SELECT * from table WHERE ...). Below is the code that was issued:
q = getEntityManager().createQuery(queryStr);
20121128_profileLogin2.jpg
Shows performance after added eclipselink.read-only = true as query hint
q = getEntityManager().createQuery(queryStr).setHint("eclipselink.read-only",
"true");
20121128_profileLogin3.jpg
Shows performance of using named query
q = getEntityManager().createNamedQuery("Orders.filterByDate");
q.setParameter("from", dateFrom, TemporalType.TIMESTAMP).
setParameter("to", dateTo, TemporalType.TIMESTAMP);

> 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 TomEE/CDI-managed-beans 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).
> Currently in production, the Glassfish 3.1.2.2 and JSF-managed-beans version
> of the web application is running much faster than the
> TomEE/CDI-managed-beans version of the web application.
> Per Romain and Mark, I ran jvisualvm to provide some benchmarks.
> Please review attached files and confirm and advise.
