The last part of the test, React-Stockcharts-SVG.ZoomTheChart, takes quite a bit time in style computation, and lots of that is in futex_wait.

I believe that time in futex_wait is the main thread waiting on the helper threads doing parallel style computation. I'm not suggesting there's nothing to optimize here, just noting that the CPU should generally be quite busy during those waits (the profiler shows this with the style threads).
