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.
