This is a comparison of on-heap and direct-heap memory monitoring metrics within half an hour. The comparison shows that the peak memory usage in the heap is similar and the performance outside the heap is the same. So, I'm a little confused. I would prefer to see Oak's performance consume less memory at the same throughput. If you can help me, I would prefer to know how your parameters would be configured under the following specifications.
