when we write large file to nas, the nifi cpu will increase quickly.
I catch some logs when nifi is writing data and stuck. The highest threads are all RUNNABLE and final step is EPollArrayWrapper.epollWait. This may the actual issue that cause cpu heavy usage.
As I know, this function should be set timeout parameter to 1ms. Can I change it by nifi configuration or others? and anyone has other different knowledge? As I know, when IO resource is not enough, the thread should be blocked or time waiting and won't cost too many cpu resource.
