Comment 2 for bug 1590804

Hmm.. fontconfig must parse those XML files at startup to do its job. While you indicate that it happens at startup of QML apps, my belief was that it happens already at login.

It may well be possible to reduce the number of fontconfig config files, but that would be a large project, where you'd need to make sure fore every single language that the rendering isn't changed adversely. AFAIK, the fontconfig and fonts-* packages currently used in Ubuntu touch are the same as on the desktop.
