Jackrabbit performance from 1.5.6 to 1.6.0

Jackrabbit, one of my favourite Apache projects, has reached version 1.6. Here's my entirely unscientific performance comparison between 1.5.6 and 1.6, using the default configuration:

Test results.  The number is operations/seconds - larger means faster.

The tests are explained here. It seems that especially when it comes to the tree traversal, there have been quite a few improvements all around. However, the store/remove performance seems to have gone down a bit. All in all, seems like a good release.
