[jira] [Updated] (NETBEANS-2408) Date.getTime() can be changed to
System.currentTimeMillis()
[ https://issues.apache.org/jira/browse/NETBEANS-2408?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
bd2019us updated NETBEANS-2408:
-------------------------------
Description:
Hello,
I found that System.currentTimeMillis() can be used here instead of new Date.getTime().
Since new Date() is a thin wrapper of light method System.currentTimeMillis(). The performance will be greatly damaged if it is invoked too much times.
According to my local testing at the same environment, System.currentTimeMillis() can achieve a speedup to 5 times (435 ms vs 2073 ms), when these two methods are invoked 5,000,000 times.
