Parallel mode execution not working

#1

Parallel mode execution does not seem to work on the version 6.2.1.
After enabling Parallel mode,i do not see multiple browsers launched nor any change in the execution time.
I have two test suites within a collection and set the execution mode to Parallel.

Any help on this is highly appreciated
