    Agocs: Boosting performance with shader binary caching in Qt 5.9
    Laszlo Agocs takes
    a look     at improvements to the basic OpenGL enablers that form the
    foundation of Qt Quick and the optional OpenGL-based rendering path of
    QPainter in Qt 5.9. "As
    explained here    , such shader programs will attempt to cache the program
    binaries on disk using GL_ARB_get_program_binary
    or the standard equivalents in OpenGL ES 3.0. When no support is provided
    by the driver, the behavior is equivalent to the non-cached case. The files
    are stored in the global or per-process cache location, whichever is writable. The result is a nice boost in performance when a program is created with the same shader sources next time.    "
