FYI, we, at a well known IT department, have been actively measuring Beam Flink 
Runner performance using MIT's Linear Road to stress the Flink Cluster 
servers.The results, thus far does not even come close to the previous 
streaming engines we have bench-marked.Our optimistic assumption was, when we 
started, that Beam runners (Flink for instance) will leave Storm & IBM in 
smoke.Wrong. What IBM managed to perform is 150 times better than Flink. 
Needless to mention Storm, and Hortonworks.As an example, IBM  handled 150 
expressways in 3.5 hours.In the same identical topology, everything fixed, Beam 
Flink Runner in a Flink Cluster handled 10 expressways in 17 hours at its best 
so far.
I have followed every single performance tuning recommendation that is out 
there & none improved it even a bit.Works fine with 1 expressway. Sorry but 
thats our findings so far unless we are doing something wrong.I posted all 
details to this forum but never got any solid response that would make a 
difference in our observations.Therefore, we assume what we are seeing is the 
reality which we have to report to our superiors.Pls prove us wrong. We still 
have some time.Thanks.Amir-

 Subject: Re: Performance and Latency Chart for Flink

I am not aware of periodic performance runs for the Flink releases.
I know a few benchmarks which have been published at different points in
time like [1], [2], and [3] (you'll probably find more).

In general, fair benchmarks that compare different systems (if there is
such thing) are very difficult and the results often depend on the use case.
IMO the best option is to run your own benchmarks, if you have a concrete
use case.

Best, Fabian
