	Performance of RRDtool will of course be affected by the number of
people requesting rendered data, but the performance difference you will
see becomes more negligible as you apply faster hardware. Further, the
benefits gained by using RRDtool far outweigh any potential performance
issues. As a counter to the 'on-demand wait', you could whip up a tool to
cron automatic graphic generation for graphics that are requested often.
The graphic rendering process does produce a static graphic, so you could
simply link against it and re-render it periodically, as you would with
MRTG. Best of both worlds.

Cheers.
