I have no idea how I'm going to make nmap faster yet. It's taking about 3-5hrs to chew through the 3k+ hosts we need monitored now, which is nice enough, I guess, but it's still painfully slow atm.

Firing off multiple instances seemed to work, but I'm not sure if that negatively impacted accuracy. Even forcing batches of 128 hosts took at least 20min per batch to finish. Something's slowing down the processing, and I'm not entirely sure what. Maybe I need dtrace...


@architect I highly recommend writing a simple tcp connect script with a short timeout(<1s) and running that in parallel. using that method, I've checked ~4k connections in about 10-15 seconds.
