Hi Mikael, having issue reproducing this. Can you help please. I can load the cluster with a bench but I'm not sure what instrumentation to use to confirm the report. all best Bogdan

You can easily reproduce it using some benchmark. But the problem is to see the regression since it only hits random transactions. The best way to reproduce is to increase the sleep time in send threads such that the outliers becomes more accentuated.
