Hi,

It took me a while but I ran the test on my laptop with 20 runs per test. I asked for a dedicated server and will re-run the tests if/when I have it.

count of partitions |   Head (sec) |    Fix (sec) |    Degradation (%)
----------------------------------------------------------------------
1000                |       0,0265 |       0,028  |  5,66037735849054
5000                |       0,091  |       0,0945 |  3,84615384615385
10000               |       0,1795 |       0,1815 |  1,11420612813371

 Concurrent Txn |    Head (sec)    |    Patch (sec) | Degradation in %
 ---------------------------------------------------------------------
 50             |   0,1797647      |   0,1920949    |  6,85907744957
 100            |   0,3693029      |   0,3823425    |  3,53086856344
 500            |   1,62265755     |   1,91427485   | 17,97158617972
 1000           |   3,01388635     |   3,57678295   | 18,67676928162
 2000           |   7,0171877      |   6,4713304    |  8,43500897435

I'll try to run test2.pl later (right now it fails).

hope this helps.
