I suggest you use 'ftbench -bc' to focus on rendering and avoid other benchmarks. You can also add '-f 0x2' to apply FT_LOAD_NO_HINTING and '-i 0-100' or so, to use some portion of good glyphs and avoid simple diacritics. I also strongly recommend 'perf record ftbench -bc...' followed by 'perf report' to find functions that take most of the time. Fedora distributes perf in kernel-tools. Good luck, Alexei
