Server Performance
7000 NTP requests per second while maintaining
accuracy associated with reference time source.
The accuracy is inclusive of all NTP packet delays
in and out of the SyncServer as measured at the
network interface. Client synchronization accuracy
to server on a LAN is 0.5-2 milliseconds (typical).
The Syncserver easily supports many hundreds of
thousands of NTP clients. NTP request handling
capacity remains the same regardless of Stratum
level
Stratum 1 via GPS: Overall time stamp accuracy
of 7 microseconds to UTC with a variation of less
than 42 microseconds typical
Stratum 1 via Dial-up modem:<50 milliseconds to
UTC (<20 ms typcial)
Stratum 2: Peering can be used as the primary
mode of operation or as a back up mode in case
the primary reference signals are lost. Time stamp
accuracy depends on NTP peer server (s).
