Dawid Weiss updated LUCENE-4397:
--------------------------------
Attachment: LUCENE-4397.patch
It's weird, the variance on this test is indeed very high. I think it may have
something to do with the fact that it spins many threads (that do i/o) so if
you're running on a multicore and there are other parallel jvms running tests
you're putting a load on the hardware. If ran in isolation things get much
faster (for me).
I've replaced some of the random() calls with the non-asserting random; I see
some difference but not that much.
> TestIndexWriterWithThreads.testRollbackAndCommitWithThreads is sometimes very
> very slow
