Subject DO NOT REPLY [Bug 50844] DateFormat.getDateTimeInstance() is very expensive, we can cache it to improve performance

We faced the similar problem for performance of log4j. Basically we log a bunch
of messages for each http request. Then, we found that http response time gets
hits. So what we ended up was to first log each message to a StringBuffer,
after some messages are logged, i.e. 100, we then call log4j api to log. This
has improved the response time. However, we still see a response hit when the
chunk of messages
are written to file.
