policyd-weight Benchmarking

I generated a benchmarking script to avoid caching.
For my test I used 50 asyncrounous processes, sending each 30 HAM and 30 SPAM request while each request was different to avoid cache-effects (DNS and policyd-weigh cache), also the requests where send over a 100mbit network, DNS requests were send over a 2Mbit uplink:

$ time ./gen-bench-mail.pl
sending 3000

real    1m11.327s
user    0m0.450s
sys     0m0.380s

Which means, inclusive network delays (DNS, querying policyd-weight on a remote machine), 3000 Mails were processed in 71 seconds.
The machine which runs policyd-weight is a Dual P3 1,2 Ghz. On this machine policyd-weight can handle 2523 Mails/Minute or 3.633.100 Mails/Day. The test is not an accurate measurement, but it gives you a figure.
Please note, that it is even faster when it can use cached data, i.e. client/domains it has already scored/evaluated.
