[jboss-jira] [JBoss JIRA] (JGRP-1406) Replace System.currentTimeMillis() with System.nanoTime()

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1406?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12665616#comment-12665616 ] 

Bela Ban commented on JGRP-1406:
--------------------------------

Only replace in time-critical code. For example, MPerf runs for multiple seconds, up to minutes, so there's no use in replcaing currentTimeMillis() with nanoTime() there.

However, TimeScheduler implementations would probably benefit from using nanoTime().

> For short timings, replace currentTimeMillis() with nanoTime(). This might get us better precision. Might need testing on Windows, where nanoTime() is apparently not implemented efficiently...
