What is going on here is that each Load Unit (virtual client) repeats a 75k
transaction over and over until the test terminates. The test creates more
load units incrementally over time until there are a total of 256 running.

The min-test would be the minimum hits-per-second or failures-per-second
respectively over all the transactions at that particular load size.

I think I will create a test that keeps the load size constant and ramps up
the transaction size. That way we can easily determine the optimal transaction
size. I have to write a different WebLoad program to accomplish this.

Once I have this test created, I will run it with various settings for MaxConn
so we can determine the optimal setting for that parameter as well.
