One more thing. There are indications that JDK 1.7 is quite a bit faster than JDK 1.6. It isn't exactly a benchmark, but here were the running times I measured for the Mondrian suite, running against MySQL on 64 bit ubuntu 11.10:
JDK 1.5.0_22 537s
JDK 1.6.0_24 420s
JDK 1.7.0_01 365s
You may be able to achieve similar improvements by upgrading to a recent JDK 1.6 (e.g. JDK 1.6.0_29), but still, it's good to have a reason to stay current.
It's nice that the JDK isn't like Windows or iOS, where every release seems to get slower. :)
