OfflineExecutor System.out Slows Down the Main Thread

[Tomahawkd]

In function readData, the while loop calls sysout in every loop, which slows down the packet parsing procedure in the terminal.
Using a timer or another thread for output to update the status string could help.

System.out.printf("%s -> Total: %d,Valid: %d,Discarded: %d, %d flows \r", 
    filePath.getFileName(), nTotal, nValid, nInvalid, dispatcher.getFlowCount());
