Bug 62374

Summary: I suggest using Externalizable instead of Serializable in RMI distribution test because implements Serializable took too much network bandwidth during high throughput loading.

Description Liu XP 2018-05-15 07:42:07 UTC 
I have captured network package by Wireshark and found there are too many package path when sending a little StatisticalSampleResult data. It used up network bandwidth during high load performance testing.

There is an article told that serialization is very easy to send more data than is required.To solve the performance problems associated with making a class Serializable, the serialization mechanism allows you to declare that a class is Externalizableinstead.
