-----------------------------
Summary: new Date.getTime() can be changed to
System.currentTimeMillis() to improve performance
Key: OAK-8233
URL: https://issues.apache.org/jira/browse/OAK-8233
Project: Jackrabbit Oak
Issue Type: Bug
Reporter: bd2019us
Location:

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 (435ms vs 2073ms),
when these two methods are invoked 5,000,000 times.
