This has been discussed several times in this mailing list. You will
find it in the archives.

- You can split the config file into several files and run mrtg on each
  of them simultaneously.
- You can use rrdtool to do the logging and 14all.cgi for the web pages.
  Look into the directory mrtg/contrib/14all or on the web page
  http://www.uni-ulm.de/~rbawidam/mrtg-rrd/
- don't use mrtg. For other programs you might check
