Out of curiousity, did your timing reveal if the main delay was due to
HLSL->GLSL translation or due to OpenGL Compile/Link time? The former we can
probably cache to disk (at least, it would be a potential solution); the latter
we can do nothing about unless glProgramBinary is available (it isn't on my
laptop).
