elek commented on issue #578: HDDS-3053. Decrease the number of the chunk writer threads URL: https://github.com/apache/hadoop-ozone/pull/578#issuecomment-600757015 > @elek , if you really think this seems to be causing issues in tests , we can change it to a lower value. I think it cause performance degradation if we use significant higher number of thread than the number of the cores. AFAIK the context switch / thread handling in Java is quite expensive (compared to the Go for example...). And it makes harder to debug the problems.
