Hi, Yes, We save the gc logs and can tell that the gc do its job that is why the total latency is very high SOMETIMES. 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

Strange latency behaviour using 1 core (in a multiple-core processor)

Hi, We are doing a benchmark test and limiting the numbers of core used by Storm. The topology contains 1 spout and 6 bolts. The first bolt has the highest load. Our experiment : we run the topology on one single machine with 4 cores. We start with 1 core and then increasing to 2, 3 and 4
