When tinkering with luci-statistics/collectd and after changing
RRD config values of /etc/config/luci_statistics and collectd,
this script can be used to delete ALL collected statistics and
restart luci-statistics and collectd
Move all eth0 IRQ processing to CPU2 instead of CPU1 which is the
default. CPU1 will continue handling all the USB interrupts which
also include USB-Ethernet adapter interrupts.
This significantly lowers the softirq load on CPU1 (from 99% to
less than 10%)
irqbalance could do the same and you can still run irqbalance
because the /etc/init.d/irq-eth-pin script will add the eth0 to
the ban list of irqbalance
See interrupt load with
while true; do clear; cat /proc/interrupts; sleep 1; done
