Hi,
While testing the network performance of FreeBSD 10 running on EdgeRouter
Lite I noticed that kernel{octe taskq_0/1} can't use more than 50% of the
cpu.
Are there any hardcoded limiting this?
PID USERNAME PRI NICE SIZE RES STATE C TIME CPU COMMAND
10 root 155 ki31 0K 32K RUN 0 21:03 56.98% idle{idle:
cpu0}
10 root 155 ki31 0K 32K CPU1 1 20:39 51.95% idle{idle:
cpu1}
0 root -92 0 0K 144K - 1 4:29 48.00%
kernel{octe taskq_1}
0 root -92 0 0K 144K - 0 4:10 43.99%
kernel{octe taskq_0}
Also, are there any other hardcoded var that can possible increase its
performance?
I can't get past 80kpps, and if you load ipfw with a single rule that will
drop by half while still using 50% of the cpus
For reference with the official EdgeRouter linux I can get:
190Kpps with hardware offload module disabled
740Kpps with it enabled, which is my test lab limit
