https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235031 --- Comment #3 from Martin Birgmeier <d8zNeCFG@aon.at> --- Next scenario: ============== 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 machine increases to 5..7 MBps, i.e., 50..70% of the available bandwidth of 100 Mbps. 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? -- You are receiving this mail because: You are the assignee for the bug.
