I upgraded to the newest JVM, and it still took 60 seconds for the initial transferFactory.init() and 60 seconds to load the first object (and its few related objects)... The CPU was near 100% that whole time.
Here is what the CF Administrator reports about the JVM now: Java Version 1.6.0_14 Java Vendor Sun Microsystems Inc.
