Hi, I extracted a small dataset that shows the problem.
you can download it from here:
https://docs.google.com/file/d/0B6o29pwkWoERdnFSaUtMNDljemc/edit?usp=sharing
I modified mdb_copy.c to demonstrate the difference. copy it to source dir
from here
https://docs.google.com/file/d/0B6o29pwkWoERd3VuUm1DN0FpcUU/edit?usp=sharing
build and
run "time ./mdb_copy foo foo2"
after this change the flag at line 64 and run it again.
at my computer the difference is 17s vs 1.7s for 3 million items.
