My first advice would be to browse pollere.net for tools - like pping (passive ping), which monitors the latency of flows in transit. That should give you some interesting information without adding any load at all. There is also connmon (https://github.com/pollere/connmon). - Jonathan Morton _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
