Re: [PATCH] Performance tests for JCR-3382

[Francesco Mari <ma...@gmail.com>]

Hi Angela,

I added another patch to JCR-3382. Tests now performsn 50.000 reads each.
The execution logic of the tests didn't change.

You can look at the tests results at [1]. I don't see a lot of difference
in performance, except for the "max" value in TreeRandomReadTest when the
default-usermanager-repository in Jackrabbit 2.6 is used.
