Shai Erera commented on LUCENE-1709:
------------------------------------

One more thing - change benchmark tests to run sequentially (by adding the property).
Robert, are you going to tackle that soon?

> The Lucene tests can be parallelized to make for a faster testing system.  
> This task from ANT can be used: http://ant.apache.org/manual/CoreTasks/parallel.html

> I'd love to see a clean solution here (the tests are embarrassingly
> parallelizable, and we all have machines with good concurrency these
> days)... I have a rather hacked up solution now, that uses
> "-Dtestpackage=XXX" to split the tests up.
> Ideally I would be able to say "use N threads" and it'd do the right
> thing... like the -j flag to make.
