Phoronix and Hammer - a followup

A while back, Phoronix published benchmarks for DragonFly 3.0.

They showed generally good numbers, but the disk test showed a
startling 250% DROP in disk speed with Hammer between 2.10 and 3.0.
The test is unpacking a certain version of the Linux kernel - pretty
simple test.  That kind of drop would be driving everyone crazy, but I
wanted to put some numbers behind saying "OMG that benchmark for my
favorite operating system is wrong and you are mean!"

There is bug 2288, which shows a small slowdown, but nothing of this magnitude:

So, I've been running the same test as the Phoronix one, at random
time on shiningsilence.com, before and after upgrading it from
DragonFly 2.10 to DragonFly 3.0.  Here's the command:

/bin/rm -rf linux-2.6.32; /usr/bin/time -o notes.txt -a tar xf
linux-2.6.32.tar.bz2

Here's the results, averaged:

39.791 - 2.10 real 	
28.509 - 2.10 user	
03.529 - 2.10 sys		

44.829 - 3.0 real	
26.137 - 3.0 user
