I’ve tested the server into two different environments: LAN and WAN. I confirm the relatively small capacity of the Soekris to support 200-300 units connected to it for NTP UDP as ideal load without alter performances.Of course the major limits comes with Ethernet , T1 and line speed. We could never get nanoseconds over there […]
