Hi,

from tests performed on 1000's of crawled images, it appears that:
  * FLIF compresses 4-7%  better, depending on content class.
  * FLIF encoding is 3-5x slower
  * FLIF decoding is ~20x slower


Some takeaway: libwebp HEAD repo already has some improvements that will be part of 0.5.0 release (for grayscale content, e.g., where FLIF performs much better). The 0.4.4 release was for fixes, so didn't include these improvements.
