> Hello,
> I found that System.currentTimeMillis() can be used 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.
