Hi Kevin,
Thanks for your interest in SwiftShader. First things first, I notice that you're using SwiftShader's OpenGL ES build. Please note that this is deprecated and will be removed soon. We are replacing it with "SwANGLE", a combination of the
ANGLE project and SwiftShader's new Vulkan implementation. Skia will integrate support for SwANGLE as part of
http://crbug.com/skia/10281.
That said, SwiftShader does not currently perform multi-threaded compilation of shaders, but does execute them on multiple threads.
Kind regards,
Nicolas
