6. Do you have a lot of data to collect?
7. Are you having preformance issues on your MRTG system?

Note that, if you switch to RRDTool, this is *only* for the data backend.
You will still use MRTG to collect the data, and so configuration is just
the same - you dont need to lose anything.  The main difference is that,
when using RRDTool, MRTG will not re-generate the graphs each polling
interval.  Instead, you use a CGI application to do this on-demand (hence
the performance win).

Lots more discussion about this is available on the RRDTool website.
