would use FI without gzip is mainly for speed.
People use FI for good compactness without suffering a processing penalty as
with gzip.

speed advantage that FI gave them originally? I'm not saying this is bad.
I'm suggesting:

As an indication, gzip time can add 30%-500% to serialization time. In our
measurements [fi serialization + gzip compression] is generally slower than
[text serialization] but faster than [text + gzip]. Then again, if your FI
doc returns high compactness your [fi + gzip] can be as fast as [text].
