A little bit of Ruby for work

I've always used, but never really like ab for looking at Apache performance. The big things that I've wanted to do with it was hit multiple urls according to a defined ratio. After a bit of hacking on the bus, I've got a working kernel (uner 150 lines of Ruby). I can run a script like this:

config = {
"http://localhost/first" => '50',
"http://localhost/second" => '30',
"http://localhost/third" => '20'}
urls = RWBBuilder.new(config)
tests = RWBRunner.new(urls, 10000, 100)
tests.report


and I'll get back a report like this:

Once I get it cleaned up a bit more, I'll release it for general use.
