I don't think so. On my usual machine:

'Trident of Fire':
Found 15124 valuable fields
Calculating valuable fields took 2094ms

'Astoria2.r':
Found 42605 valuable fields
Calculating valuable fields took 8847ms

We have to think about slow machines too.

Sorry that i couldn't find time to provide more values.
