Knut Anders Hatlen commented on DERBY-3619:
-------------------------------------------
Now the CLOB test is part of the nightly regression suite and the results are
published at http://home.online.no/~olmsan/derby/perf/. The test doesn't show
the above mentioned regression (DERBY-3312), probably because the nightly
regression tests run the clients on a different machine than the server. In
fact, the tests show a ~50X speedup for the client/server test from 10.2.2.0 to
the current trunk when running a single-threaded test.

> I'm planning to add some more load types to
> org.apache.derbyTesting.perf.clients.Runner so that we can run tests whose
> load is roughly equivalent to the tests run in Olav's nightly performance
> regression tests - http://home.online.no/~olmsan/derby/perf/. Having such
> tests available would make it easier to investigate performance regressions
> reported by those test runs. Currently, we have clients under
> o.a.dt.perf.clients that generate load that is similar to the single-record
> select and single-record update operations with primary key and the primary
> key join operations (in fact, the nightly regression tests have used the
> tests in derbyTesting.jar for these types of load for about a month now).
> For the following types of load, we don't have test clients in
> derbyTesting.jar:
> 1) tests for insert performance
> 2) tests for delete performance
> 3) single-record select + single-record update on secondary index
> 4) single-record select + single-record update on non-indexed column
> 5) TPC-B like transactions (should probably be called something else, but I
> think it's useful to have a test that uses the same schema and queries as
> described in the TPC-B spec)
> (3) and (4) are just variants over the existing single-record tests.
