[imp] Seeking advice on slow login times (follow-up)

[Walter R. Moore]

Any advice on the benchmarking process? White-papers, etc? Any cool
horde plugin that can tell me horde is doing during the login wait?

I have done various routine things like straces, but web servers and php
don't make it as easy to watch a process like this from start to end.

Thanks again,
-Walter Moore
