While it is most commo= nly in the "last mile" or wifi hops, on some ISP's you'll find bloat inside their network, and/or peering points between your ISP and where the test server is. Sometimes it's like a willow the wisp, and moving from minute to minute..... (or second to second, between an ISP and your WiFi hop, when the two hops have similar goodput). Whenever you detect bloat, your next (ideally simultaneous) action is to diagnose which hop(s) are problematic. - Jim =E2=80=8B > > Mine is win10, latest Realtek GBE driver with 1 buffer in upload, and sen= d > offload disabled; > > ??? > > > > _______________________________________________ > Bloat mailing list > Bloat@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/bloat > > --f403043af58875f745056464b5ae Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable
