#1475: varnishncsa's ttfb is potentially dishonest
 Reporter:  daghf     |      Owner:
     Type:  defect    |     Status:  new
 Priority:  normal    |  Milestone:
Component:  varnishd  |    Version:  trunk
 Severity:  normal    |   Keywords:
 Time to first byte in varnishncsa is taken from the VSL timestamp record
 tagged 'Process', which is taken /before/ vcl_deliver has been executed.
 Hence any significant processing in vcl_deliver will not impact the
 reported ttfb as one might expect, and it will simply be inaccurate ..
