try to find out why sudo tests on centos systems are so much slower #880

The sudo tests on build.rexify.org for CentOS / Fedora systems are slower (2x) than on debian/ubuntu systems.

We need to figure out if this is a problem with rex or a problem with the system.

At the first glance it seems to be a problem with the remote system detection. It checks again and again a lot of things on CentOS. Probably it does not fill the connection cache well, or something like that.
