The minimum sleep time between ntpd upstream requests is 64 seconds. With 64000 clients an ntpd server must answer one thousand requests per second.
If the client ntpd clocks are very stable they will ratchet back to one request every 1024 seconds (about 17 minutes) so the same 6400 clients would only make the server process 62.5 requests per second. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/229632 Title: ntpd should run niced To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/229632/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
