Help in tracking down performance issue in telegraf + opcua input plugin (1s interval not keeping up)

[R290]

Is the 1s interval a hard requirement? Otherwise you could try the telegraf/plugins/inputs/opcua_listener at master · influxdata/telegraf · GitHub instead? Telegraf is able to repeat non-frequent data changes if needed, see: Replication of Non frequent data change - #6 by JeroenVH
