Hi.
What is the status for software flowid calculation? I found the old netisr2
patch[1] from Robert Watson and took from there code for setting flowid in
tcp_input with some changes[2]. It work for me very well (8.1-stable) - now the
server can handle not transit traffic without drops up to 118Kpps 60MB/s
incoming and up to 107Kpps 50MB/s outgoing, netisr dispatch packets via three
threads by round-robin:
12 root -44 - 0K 336K CPU2 2 18:43 56.15% {swi1: netisr 2}
12 root -44 - 0K 336K RUN 3 18:41 54.49% {swi1: netisr 3}
12 root -44 - 0K 336K CPU0 0 18:39 50.39% {swi1: netisr 0}
12 root -68 - 0K 336K WAIT 1 8:01 18.07% {irq256: bge0}
So, what the reason to exclude this code from final version?
