Hi, Yes, you're correct. After my adjustment, it can process 5500 tuples/s of whole topology. And I do a simple experiment: a. CountingBolt only: 11500 tuples/sec b. CountingBolt+parseDataBolt: 6000 tuples/sec
These two bots are both connected from kafkaSpout, so I think parseDataBolt is the bottleneck!! BUT!!! I try to increase the parallelism hint of parseDataBolt from 20 to 50, and it almost has no effect of throughput. What's the problems? If I need to process more tuples in the future, what's the solution ?

The bottleneck seems to be somewhere else.
