If you use the sample data from the example, there must be an issue with the setup.
In Flink's standalone mode, it runs in 100ms on my machine. It may be possible that the command line client takes a long time to start up, so it appears that the program run time is long. If it takes so long, one reason may be slow DNS resolution. You can check that by looking at the logs of the client process (int the "log" folder).
