I compared strace output between the 2.2 and 1.7.28 installation and it
seems, that loading the dll files before the cygheap_user log entry is
responsible for the time lag.
If I look to the strace output from 1.7.28 the following lines (without the
dll loads) are shown:

Yes, this Version has nsswitch.conf in the default configuration (with db
entries) so you see the pwdgrp log entries but it is very fast.
Perhaps this helps in finding the problem.
