thanks Damian
I was able to reproduce the observed problem with an isolated test
scenario. So I recreated the components ARQ, CORE, IRI, and TDB with the
SVN state of May 15 9 (so svn update -r {2012-05-15} and then svn clean
install)
I then created a simple test program (attached as
PerformanceRegressionTest.java) which I ran 4 times in a row for each
version of Jena. Note that I deleted the TDB directory after the first 4
runs before using the other Jena version. Attached are the files with the
output. The regression is obvious
Andy: could you please take a look at what would have caused this and if
the performance regression is unavoidable. Note that we are talking just
about write operations, no queries, no release store or anything like
that.
thanks
Simon

You can check out the state of the repository at a particular date using:
svn update -r {2012-05-15}
