I'm very happy to continue testing; I was merely meaning the 1.7.35 performance is still not adequate in my environment. > It would be nice to know what part of the code is so slow.

I have made some progress with analysis (slightly handicapped as I'm a novice with ldap and am not an admin) According to nltest /dclist: Our environment has 6 London based DCs According to ldp.exe Live Enterprise Tree we have a tree structure for LDAP. 6 leaf nodes at the top matching ther 6 DCs 4 leaf nodes under an "AUS" (Australia) node 3 leaf nodes under a "CHI" (Chicago) node and a few more similar to this in other regions. When running mkpasswd I see active sessions to all the nodes in the tree on port 389 (ldap) I have tried using Sysinternals ADInsight (with a 32bit cygwin) to see what requests are made with 'echo.exe' There are two searches shown: A) RootDSE:LDAP_SCOPE_BASE:(objectclass=*) (1.113ms) B) <London DNS>:LDAP_SCOPE_SUBTREE:((objectClass=trustedDomain) AND (name=<Australian DNS>)) (4.426s) I don't know why the second query is being made with the Australian DNS name but I suspect this is the problem. (Perhaps it as simple as A coming first in the alphabet ...) Happy to investigate further if someone can suggest some useful avenues.
