I seem to be getting a consistent failure on the first batch of IPv4 throughput tests, although the IPv6 tests before it worked fine: =3D=3D=3D perf/passt_tcp > passt: throughput and latency Throughput in Gbps, latency in =B5s, one thread at 4.8 GHz, 8 streams MT= U: | 256B | 576B | 1280B | 1500B | 9000B | 65520B | = |--------|--------|--------|--------|--------|--------| TCP throughput over IPv6: guest to host = | - | - | 6.5 | 7.6 | 20.7 | 28.1 | TCP RR latency over IPv6: guest to host = | - | - | - | - | - | 74 | TCP CRR latency over IPv6: guest to host = | - | - | - | - | - | 227 | = |--------|--------|--------|--------|--------|--------| TCP throughput over IPv4: guest to host = | 0 | 0 | 0 | 0 | 0 | 0 | TCP RR latency over IPv4: guest to host = | - | - | - | - | - | I haven't seen a failure like this before, has anyone else seen something like this? I'm not getting any messages from the iperf client at all - like it has no connectivity whatsoever, but the non-perf tests are all passing. Haven't done much troubleshooting yet. --=20 David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.
