The default sampling method is method 3. The documentations are about 
the old method 1. The settings given are not good for method 3.

Remove intervals 9. It realy bogs you down. Default to intervals 1 and 
MUST be left at that value.

Use samples 9 instead. The second samples value is totaly ignored and 
best left out.
Also, remove ratio 0.9. It's no longer needed.

You can also leave confidence and variance out and use the default values.
This gives something like:
interior{ media { scattering { 1, rgb 0.03 } samples 20}

This will be much faster and gives the same, or beter, result.

As said, scatering is the slowest kind of media, but you can make it 
even slower with bogus parameters.
