It seems odd, but the test shows the 64-bit kernel as running disk
transactions vastly faster than the 32-bit (page 5).  Its using PostMark
which is a filesystem benchmarking utility.

64-bit - 2297 TPS
32-bit - 235 TPS

How in the world does a 64-bit cpu make your disk reads/writes happen 9x
faster?  How did that not raise a big red flag for the person performing the

Since the tester didnt put in any real comments about the hugh difference in
a highly unexpected area, im a big skeptical about all of their tests.
