RFR[8237480]: Add micros for DatagramSocket send/receive

[Patrick Concannon]

Hi,


Could someone please review my webrev for JDK-8237480 'Add micros for 
DatagramSocket send/receive' ?

This change adds some benchmarks for the DatagramSocket::send and 
DatagramSocket::receive methods.


bug: https://bugs.openjdk.java.net/browse/JDK-8237480

webrev: http://cr.openjdk.java.net/~pconcannon/8237480/webrevs/webrev.01/


Kind regards,
