Hi, Prof.Luigi RIZZO
Firstly i should thank you for netmap. I tried to send a e-mail to you
yestoday, but it was rejected.
I used two machines to test netmap bridge. all with i7-2600 cpu and intel
82599 dual-interfaces card.
One worked as sender and receiver with pkt-gen, the other worked as bridge
with bridge.c.
as you said,I feeled comfous too when i saw the big packet performance
dropped, i tried to change the memory parameters of netmap(netmap_mem1.c
netmap_mem2.c),but it seemed that can not resove the problem.
60-byte packet send 14882289 pps recv 13994753 pps
124-byte send 8445770 pps recv 7628942 pps
252-byte send 4529819 pps recv 3757843 pps
508-byte send 2350815 pps recv 1645647 pps
1514-byte send 814288 pps recv 489133 pps
sender command: pkt-gen -i ix0 -t 500000000 -l 60
receiver command: pkt-gen -i ix1 -r 500000000
bridge(other machine) command:bridge -i ix0 -i ix1
can sender and receiver on a same machine ?
thank you for your reply.
