Fw: [Pool] ntp server performance and score

[Gary E. Miller]

Yo All!

See below for an interesting message that poppod up on pool at lists.ntp.org.

This guy is serving almost 5k ntp requests a second.  If each client is
making one request every 60 soncds that is about 300k clients!

Sadly he points out that chronyd can keep up, but not nptd...

BTW, we really neat to figure out a cool group nickname...

Subject: [Pool] ntp server performance and score


there are few public ntp server in China, we have two ntp servers to
join the pool.


we set the speed to 25Mbps, so the ntp traffic is about 4939.8
packets/sec. the NTP server could not keep up requests, then the score
is down.


if we upgrade to chrony, it can keep up the requests.


how can i tuning the ntp server performance?


how the ntp score is calculated? i find the score is drop sometime even
though it have stable time reference and network connection.
