Hi to all, I finished implementing the multi-queue / multi-channel in stmmac and I am now making some tests.
The mechanism is working properly, but the performance could be better (~440Mb/s) :). For measuring I am using iperf: synopsys@pt02ipk1:~$ iperf -c 192.168.0.3 --port 5001 -t 20 -i 5 ------------------------------------------------------------ Client connecting to 192.168.0.3, TCP port 5001 TCP window size: 85.0 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.0.2 port 34272 connected with 192.168.0.3 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0- 5.0 sec 260 MBytes 436 Mbits/sec [ 3] 5.0-10.0 sec 262 MBytes 440 Mbits/sec [ 3] 10.0-15.0 sec 262 MBytes 440 Mbits/sec [ 3] 15.0-20.0 sec 257 MBytes 431 Mbits/sec [ 3] 0.0-20.0 sec 1.02 GBytes 437 Mbits/sec I am seeing tx being performed in all queues, but rx is just being routed to queue 0. The reason why only queue 0 is processing the packets is because I am using priority tagged routing for now and iperf is not capable of producing priority tagged traffic. I am sending you this e-mail in order to know if you could suggest me a tool to generate priority tagged traffic and if you have experience in tweaking stmmac to improve performance. Thanks, Joao
