The google type library is not representative as they do not propose full
fonts but fonts cut down to the few hundreds of glyphs necessary for latin.
The smallest the font the closest the size will be to a preview file.

Typical full-featured modern fonts (even excluding cjk fonts) are a lot fatter.

The rpm uses the pdf upstream provided, you can ask the packager to remove it
or split it in a separate package

It's more resource-intensive server-side and the whole speed depends on your
network pipe. If you have a fat network pipe you do not need a "font store",
just install all the font packages in Fedora and be done with it.
