Re: 8 hours tests ends with inconsistent DB.
I apologize for not using the term "benchmark" correctly. One may have
different expectations about the result of a "benchmark":
b) comparable results
if b) applies you are right about missing specs, but I guess the OP
just wanted to test the limits of OL and the issue was not poor
performance but corrupt DB and lack of stability under extrem load.
You cannot blame Sleepycat for that (bugs aside).
At Zope Corporation (-> Open-Source web application server Zope) we had
several very intelligent people trying to develop a data storage
backend for Zope using BerkeleyDB for a couple years. Just a few weeks
ago that attempt was finally given up on. We were unable to work around
all the BDB weirdnesses and a lot of the time it seems Sleepycat wasn't
all that responsive when it came to bugfixes (several were uncovered by
our work) or suggestions. I would not be surprised if at least some of
those corruptions can be blamed squarely on BDB bugs.
