Also, it would be nice to know what are the callers of freettype that consume the most time.
As a reminder here is where I got last time with kcachegrind: https://www.mail-archive.com/lyx-devel@lists.lyx.org/msg194401.html The caching in Qt5 seems much lower-level than what you have access to, so it is not impossible that you can no longer get good performance with Qt4. Let us hope that your patch works.
