[mrtg] Re: Making MRTG more Efficient/Faster

[Tobias Oetiker]

Hakan,

to make mrtg faster, apart from using rrdtool you should


* use only one instance and configure Forks: instead

* run mrtg in daemon mode so that it does not have to reload the
  config on every round.

* make sure that you do not throw away error messages it produces.
  It could be that it is redoing its confcache population routine
  on ever run.

cheers
tobi
