The other item to note is that the log event will carry an additional long, which will take up that much more memory. This is likely inconsequential in the big picture as well, but worth mentioning in this discussion. And yes, try it out and measure it :-)

> Add a token in the log format specifier to output the current value of {{System.nanotime()}}.
> We are currently adding the nanotime value to our log messages manually, which we find very useful for troubleshooting unexpected latency, and as a quick-and-dirty data source to feed into performance analysis tools.
> It would be very nice if Log4j could do this for us. It would also be nice to have this in the log format specified, so we can turn it on/off at runtime by editing the Log4j config file.
