Re: 2.1 & 2.2 statistics, and some odd behavior that needs to be examined.
It will help to locate the probelm if you can further obtain a vmstat trace
for the first four rows of the last table of the performance result page,
BTW, when it comes to the search performance, the hashing DB performs
better than the btree by more than 10% when shared memory is not used,
and this conforms to what I observed in one of my experiments.
With the share memory, however, they appear almost on par...
