Hello, i don't know if this helps or is related to the problem, but i also had/have trouble with networking on FreeBSD DomUs, particularly with packet forwarding. For this purpose i'm running NetBSD 7.0 as a virtual router, because OpenBSD 5.9 seems to have the same problem. Perhaps this might h

I just noticed that these performance problems do not occur under 10.0 and 10.1. Starting with 10.2 IPv4 TCP performance drops from ~12 Gb/s under 10.1 to ~350 Mb/s under 10.2. Should i write a new bugreport for this? > On 09 Sep 2015, at 22:58, Sydney Meyer wrote: > > Hello,

Hello everybody, i have noticed some odd behaviour with networking under Xen with FreeBSD 10 as a DomU. - IPv6 (TCP) bandwith drops from ~10 Gbit/s IPv4 to around 3 Gbit/s IPv6. (measured with iperf) - Dropped/Stalled Connections with TCP Segmentation Offload and pf enabled. - IPSEC-enabled K
