General guidance here is these values should be set to 2 times the number of available cores and no more then 4 times the number of available cores on a single instance of NiFi. If you are running a NiFi cluster, these values are enforced per node. So a setting of 16 in a 4 node cluster equates to a total of 64 threads cross the cluster. Setting values to high just results in many more threads in cpu wait and will not help performance at all.

Beyond increasing these value you need to be mindful of how many concurrent task you assign each of your processors. Some processor are more cpu intensive then others (meaning they take longer to complete a job holding the thread much longer). You can look at the "tasks/time =: stats on a processor to see if it thread are long or short running. For processors that have long running threads you want to be extra careful on how many concurrent tasks you assign them.

Thanks,
