Is there any suggested ratio for dividing the number of handler threads between normal RPC and service RPC (HDFS)?

Is there any suggested ratio for dividing the number of handler threads between normal RPC and service RPC (HDFS)?

How should we reassign the current number of hdfs.namenode.handler.count to dfs.namenode.service.handler.count and hdfs.namenode.handler.count after activating service RPC?

For instance, we currently having 240 handler threads - should we set dfs.namenode.service.handler.count to 120 and hdfs.namenode.handler.count to 120 or do you suggest other ratios?

Thanks for helping me out. For others' information: ~50% of dfs.namenode.handler.count is a reasonable value for dfs.namenode.service.handler.count.
