-------------------------------------

[~shawkins]. You can find the test result here: [mojo page|https://mojo.redhat.com/docs/DOC-1083297], [pdf report|https://mojo.redhat.com/servlet/JiveServlet/download/1083297-5-1128278/dv_6.2.6_perf.pdf].

I do not see same issue as with 6.3.0. In general, I see very similar results in compare to 6.2.0.GA. I have run test for set 02 (problematic set) and two more sets, just to confirm results.
