title: MP4 slow start for large file
body: <p>I have a server that stream mp4(h264). I use MP4Box to put the moov atom at the beginning of a file and interleave default 500 ms.</p>
  
  <p>However, I noticed that at peak times when the server is busy, the files start streaming slower, but not same slower, large videos (one hour or more) start much slower than small files.</p>
  
  <p>I read about Atom Moov being processing slower in a lighttpd with h264 streaming module like mine...</p>
  
  <p>Any way I can speed up playback start to about 2 seconds, right now it's about 7 for large files...</p>
