> Hello,
> I found that Date.getTime() can be changed to light method 
> System.currentTimeMillis(),which can avoid creating the temporary Date object.
> new Date() is a thin wrapper of 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 (435ms vs 
> 2073ms), when these two methods are invoked 5,000,000 times.
