Hi everybody, I’m trying to do some preliminary tests with storm, to understand how far it can go. Now I’m focusing on trying to understand which is his maximum throughput in terms of tuples per second. I saw the benchmark done by the guys at Hortonworks (ref: https://it.hortonworks.com/blog/microbenchmarking-storm-1-0-performance/ <https://it.hortonworks.com/blog/microbenchmarking-storm-1-0-performance/>) and in the first test they reach a spout emission rate of 3.2 million tuples/s.
I tried to replicate the test, a simple spout that emits continuously the same string “some data”. Differently from them, I’m using Storm 1.1.1 and the storm cluster is set up on my laptop, anyway I’m just testing one spout not an entire topology, but if you think that more configuration information are needed, just ask. To compute the throughput I ask the total amount of tuples processed to the UI APIs each 10s and I subtract it by the previous measure to have the amount of tuples int the last 10s. What the mathematics give to me is something around 32k tuples/s. I don’t think to be wrong saying that 32k is not even comparable to 3.2 million. Is there something that I’m missing? Is it normal this output? Thank you for your help and for your time, Alessio
