only start every odd numbered script in the back ground to spread the
load a bit. i do this in all my mrtg setups, for example
--- script called by cron ---
mrtg setup1.cfg &
mrtg setup2.cfg
mrtg setup3.cfg &
mrtg setup4.cfg
---end script----
I've got scripts called every 5 minutes, 15 minutes and 30 minutes,
so at some points they overlap, and I have no high usage spikes.
