Are there any production setup with jit.off()? This measurement would be
artificial I think.
Anyway, I collected the results and they are quite noisy again (~10%
variation). I would not say anything based on them. But in average ffi
call gives -0.5% (worse) and ffi call with caching -1.0% from the
baseline (master). Maybe it is just noise.
WBR, Alexander Turenko.
