https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=165059 --- Comment #44 from void@f-m.fm --- (In reply to Mark Linimon from comment #42) In terms of iperf3, i.e. throughput, it's not really a workaround. Setting hw.vtnet.tso_disable="1" hw.vtnet.lro_disable="1" hw.vtnet.csum_disable="1" in the freebsd guest increases throughput by 5-20% but it's never linespeed for *any* version of freebsd guest. It *is* near linespeed for linux guests. The context here is freebsd host. -- You are receiving this mail because: You are on the CC list for the bug. You are the assignee for the bug.
