Oh I see, you were using your group commit type
so even with only a few commits per second, you'll
numbers of entries per second.

The disk used in the
experiment is the Seagate ST336753LC (15K RPM). Write caching was
disabled in the experiment.

From experiments, I didn't see a significant
reduction in the population time by the removal of the transactions. The
experimental data shows instead that it is the number of database operations
which has more effect on the performance of the directory
you tested on a disk with write-back-caching ?
Otherwise you should be seeing only a few tens of
commits per second due to physical disk rotation
