APPENDIX 3: Scheduling issues.
==============================
As seen NAPI moves processing to softirq level. Linux uses the ksoftirqd as the
general solution to schedule softirq's to run before next interrupt and by putting
them under scheduler control. Also this prevents consecutive softirq's from
monopolize the CPU. This also have the effect that the priority of ksoftirq needs
to be considered when running very CPU-intensive applications and networking to
get the proper balance of softirq/user balance. Increasing ksoftirq priority to 0
(eventually more) is reported cure problems with low network performance at high
CPU load.
Most used processes in a GIGE router:
USER PID %CPU %MEM SIZE RSS TTY STAT START TIME COMMAND
root 3 0.2 0.0 0 0 ? RWN Aug 15 602:00 (ksoftirqd_CPU0)
root 232 0.0 7.9 41400 40884 ? S Aug 15 74:12 gated
