AFAIU QtQuickCompiler has nothing to do with memory management, its main purpose is reduction of start up time and obfuscation of sources.

Note that measuring FPS above screen refresh rate (usually 60) does not make a lot of sense, as underlying graphics systems may not preserve it (and if vsync is enabled, screen refresh rate is a hard upper bound).
