Hi, We are running a topology on one machine and limiting the number of cores that can be utilized by storm. The machine consists of 4 cores, and we do tests on 1 core, 2 core, etc.. However, we can not explain this strange behaviour which only occurs when we run the topology with 1 core. The strange behaviour: we run the topology several times and approximately , 3 out of 10 tests, we got very bad throughput which is about 50% of the normal throughput even though it is the same topology and test.
Thanks
