Note you don't HAVE to use indirect lighting, although everyone would like to; even when they fix the splotch artifact problem, it's still going to be a lot slower rendering with indirect lighting/global illumination enabled, than it will ever be with it disabled. That is true in all rendering applications, global illumination takes a lot of CPU time to calculate.
One thing to check that can really kill your render times: look at the min shading rate on the properties tab of the hair (for each body part, if it's a conforming hair figure). Some vendors set it to 0.0, which is probably way higher than you need; make it 0.1 or 0.2 if so.
