Bartosz Majsak commented on ARQ-1440:
-------------------------------------

I ran int-tests module against Oracle11g profile, and here are the results:
* 1.0.0.Alpha6 (few tests failing with SQL scripts as I introduced proper handling recently) : 8:35s
* Current master: 4:09s
There are few changes I did on master:
* moved back to the [single database connection for the test method|https://issues.jboss.org/browse/ARQ-1131]
* disabled forking for surefire (that was actually huge penalty for my tests, but this have been introduced after releasing 1.0.0.Alpha6)
* [made filtering by primary keys optional and disabled by default|https://github.com/arquillian/arquillian-extension-persistence/commit/54cf07dfee4d5bf678128d2382d5a27a74e3bc85]

Would it be possible for you to build latest snapshot from master and run your tests against it if that is quicker than sharing your test cases?

> I updated my Arquillian environment to 1.1.0-Final, Arq persistence ext 1.0.0a6 and Arq 1.0.0a3 FROM Arq 1.0.1, persistence 1.0.0a5 (no tx ext in that env since it was part of the persistence ext) and my Arquillian persistence tests which deploy to a managed Glassfish container take over 3x as long as they did in the old environment. 
> For example one test which took 13s to run in the old environment now takes 44s.  
> This slow down only seems to affect tests which use the persistence extension. 
> Arquillian tests which do not use the persistence extension take the same amount of time as they did in the old environment. If I switch the environment back I see the performance goes back up for persistence extension tests.
