The title says it all actually. From tests with barber shop scene here gives 2-3x speedup for shader compilation on my oldie i7 machine. The gain is mainly due to textures metadata query from jpeg files (which seems to requite de-compression before metadata can be read). But in theory could give nice improvements for scenes with huge node trees as well (i'm talking about node trees of complexity of fractal which we had reports about in the past).
