  Wrong.
  Yes, it is faster with some things. With other things it's quite a lot
slower (like a magnitude of 5:1 or so).

  It's very misleading to take a lightflow image and then try to make an
almost exact copy of the image made with povray and compare the rendering
times.
  If you try to simulate the lighting model of one renderer with another,
you usually have to make compromises which make the latter slower.

  I bet that if we make the test the other way around, that is, take a
povray (or megapov) image which is very fast to render (and has something
special) and try to achieve the exact same image with lightflow, it will
be quite slow.

: and it has great radiosity.

  I haven't yet seen a radiosity lightflow image which is considerably
better than megapov radiosity.
