Mikael Ståldal commented on LOG4J2-1395:
----------------------------------------
OK, what about this:
Write directly to <code>java.io.FileDescriptor</code> and bypass
<code>java.lang.System.out/.err</code>.
Can give up to 10x performance boost when the output is
redirected to file or other process.
Cannot be used with Jansi on Windows. Cannot be used with
<code>follow</code>. Output will not respect
<code>java.lang.System.setOut()/.setErr()</code> and may get
intertwined with other output to
<code>java.lang.System.out/.err</code> in a multi-threaded
application.
<i>New since 2.6.2. Be aware that this is a new addition, and
it has only been tested with Oracle JVM
on Linux and Windows so far.</i>
> Faster Console appender
