I would attribute the regression to my testing setup. Running a couple
of the tests again, I get numbers more in line with stable and release.
In addition, I was probably not as careful with current as we will not
be running it in production. I will see if I can find the time to run
the numbers again and update the table.
FYI, this first round of testing was to answer the question, does using
threaded bind help performance on FreeBSD? In this minimal test case, it
does. With the above info, I can now look into how a bind vs threaded
bind performs in different test cases. This also gives me information on
what I will gain/lose when deciding on various administration issues.

I modified the kernel configuration files that where included with the
distribution. For release, stable and current, I created four kernels;
uni-processor, uni-processor with polling, multi-processor, multi-
processor with polling. The OS was as default as possible. For this
test, I didn't want to make many changes.
