That test is almost as bad as it can ever get. Given that enumerating all AD accouts with mkpasswd takes about 2 hours and I'm doing something very similar here, I'm not even surprised. I was more surprised to see the server go so fast, but my guess is that it can use jumbo frames to talk to the AD. >> While that hurts, the more usual case with many files from the >> same user doesn't feel any slower at the moment.
