IPA performance

Bret Wortman Tue, 27 May 2014 06:50:47 -0700

I just checked to be sure, and we do already put all the IPA servers in our client host tables just to be sure they can be reached even if DNS goes down.

Crud. That was supposed to have a second comparison log too:

I think this shows, roughly, a 7 second elapsed time from start to
finish, right? Granted, there were other request being serficed during
this interval as well, but nothing that looked like outrageous volume.

I don't see anything unusual here. The directory server retrieved the
data just as fast on both systems, the difference appears to be the
network, in connection and shutdown times.

+1, however the TLS handshake took longer. That probably required several DNS lookups so I wonder if DNS lookups might be slowing things down. I wonder if putting server records manually into the hosts file would make a difference. If yes then may be you need to take a look at your DNS setup for the slow network.

On our faster network, this same exchange went much faster:
