[squid-users] --foreground vs -N

[B. Cook]

tl;dr:
is there any functional difference between the two?


Using runit to handle my squid processes.

I have Observium graphing system information.

My data/traffic is consistent

In my run file I changed from squid -N to squid --foreground

#!/bin/sh -e

exec \
chpst -o 131070 \
chpst -e ./env \
/usr/sbin/squid --foreground -s
# /usr/sbin/squid -N -s

I made the change at 10:30 and the cpu usage increased.

(bandwidth has trend applied)

I can not tell from the graph if 'performance' increased or 'latency'
decreased.. but cpu usage certainly did increase.

I have no workers defined.

If you can't explain it simply, you don't understand it well enough.
