----------------------------------------
Every day?
See http://home.online.no/~olmsan/derby/perf/ , accessible from
http://dbtg.foundry.sun.com/derby/test/ .
Since the results don't make sense without comparing them over time (on the
same hardware, os, JVM, etc), I don't think they're well suited for running as
part of suite.All. Note also that the results can be rather unstable, so to
draw conclusions one has to look at the numbers for a longer period of time.
I don't know if there are any other performance test comparing performance over
time for Derby.

> DERBY-4565 added a concurrency test for sequence generators to test the
> possible race condition for allocating a new range of pre-allocated numbers
> for the sequence. I have been looking at enhancing that test to provide
> similar test for identity columns. I plan to add another command line
> parameter to the test which will run the concurrency test to stress identity
> column generator.
