Some findings...
I have added some counters in the code (ahhh, 24 years back in the past,
when I was adding printlf() in my C code ;).
Here is what I found :
- most of the time is consumed in the CachedRecordManager.update()
method, which calls BaseRecordManager.update( long recid, Object obj

Hi Emmanuel,
I modified a test and the JdbmTable implementation to expose exactly which
data structure is being used and make sure the switch occurs at the
appropriate time. The tests really were not

I'm still looking for a fast/cheap index data structure that can be
sparsely populated, is lossless, and scales to billions of entries.
(Currently our index is fast/cheap but lossy. If you fill a slot with a
million entries and then remove every other one, it

Hi,
while doing some perf test on the Add operation, I'm getting blocked
after having added around 3800 entries. After investigations, I found
that some index are very expensive to update :
- the ObjectClass index quickly get saturated, and adding a new entry
into it cost a hell of a time.
