https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235031 --- Comment #3 from Martin Birgmeier <d8zNeCFG@aon.at> --- Next scenario: =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D If I run iperf -c hal -b 500m,0 i.e., using only 50% of the available bandwidth between the laptop and the third machine, NFS read performance between the laptop and the second machi= ne increases to 5..7 MBps, i.e., 50..70% of the available bandwidth of 100 Mbp= s. It seems that in this case there is sufficient but not too much activity on= em0 in order to optimally talk to the second machine. Maybe this is a case of lost or stuck interrupts? Or some problems with handling UDP? --=20 You are receiving this mail because: You are the assignee for the bug.=
