            Bug ID: 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.
           Product: JMeter
           Version: 4.0
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Main
          Assignee: issues@jmeter.apache.org
          Reporter: liu_xp2003@sina.com
  Target Milestone: ---

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.
