That's a nice result.

However, I don't quite understand this result for the older DLL.
Weren't you reporting >4 secs as startup time from 1.7.35?!?

On another note:

I just uploaded a new developer snapshot (2015-02-24).  This snapshot
should improve mkpasswd/mkgroup or, generally speaking, enumerating AD
accounts, a lot.  Can you give it a try?

While you're at it, does the new snapshot still stop after 3.5K accounts
even though you think there are 8K accounts?  If so, I'd be interested
to investigate this further.  The reason is, while testing my today's
performance improvements, I stumbled over a bug in my code which also
resulted in enumerating less accounts as desired.  So I'm not entirely
sure your problem isn't related to a bug either.


Thanks,
Corinna
