Consider a web company who gets 5Mbps of transfer request 99.9% of the time and 1000Mbps of transfer request 0.1% of the time. Would you tell them that a 10Mbps internet connection is (obviously) not high enough? Would you consider it a bug if their machine rebooted every time they got more than 10Mbps in requests? Consider cdrom.com. Would you consider it a bug if freebsd rebooted every time they received 5001 simultaneous connection requests and tell them to tune their FTP server correctly? How am I supposed to test my system, both hardware and software, if I can't push them to their limits?
