Lack of entropy is what causes super slow login. I creates some tokens on login that use up entropy. However once you have logged in it re-uses the token and the entropy should not be an issue after that for the most part. He didn't actually say but I suspect that after the initial minutes wait for the login, it was not THAT bad after that. Not like what we are seeing with your system. _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
