In all of the following tables, the best performing result in each row, is
assigned a relative value of "1" and shown in bold, so a score
of "2" means <span class="emphasis"><em>"twice as slow as the best performing
result".</em></span> Actual timings in seconds per function call are
also shown in parenthesis.

with 2Gb of RAM and running either Windows XP or Mandriva Linux.

As usual with performance results these should be taken with a large pinch
of salt: relative performance is known to shift quite a bit depending upon
the architecture of the particular test system used. Further more, our
performance results were obtained using our own test data: these test values
are designed to provide good coverage of our code and test all the appropriate
corner cases. They do not necessarily represent "typical" usage:
whatever that may be!
