title: Suggest very fast (microseconds) java logging?
body: <p>I want to track events in my sound processing multithreading app. It has some bug manifestating only under certain circumstances. </p>
  
  <p>If I am trying to use conventional logging (slf4j and log4j to console intercepted by Eclipse), bug disappears since logging commands introduce millisecond level delays and everything goes differently.</p>
  
  <p>How to make logging go faster (hundreds or thousands of times) or to log other way?</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>Now using logback with file appender and it is sufficient yet.</p>
