[mrtg] Config File Size

This might have been answered previously, but a quick search through the
archives did not yield the results I wanted.  Anyway, is there a practical
limit on the number of interfaces to monitor in a single config file?  For
instance, are there significant performance drop-offs if one config file
contains several thousand interfaces?  I believe that the data collection
probably isn't affected too much, but would the drawing of the graphs and
pages be affected by having to parse such a large config file?  Do people
have experience with how large they let their config files grow before
splitting them into different files?  I guess I'm looking for a trade-off
between many small files with many processes and larger files with fewer
processes.  I'm already using rrdtool to elimininate the time spent creating
graphs and such, so I guess I'm looking for a way to optimize my current
settings.  Any help that can be provided would be appreciated.

Best Regards,

David Cheng
