OK, 2 things to speed up rendering:

IC is set at 95, That is overkill. Set it to 32. Go to 50 if required (rarely) => See below

Pixel Samples at 6. That is way overkill. Use 3 for normal, and 4-5 as max. => See below

MSR. set at 0.21? That is a strange number. Set at 0.2 or 0.5. => See below

I use :
RB at 1
IC at 0 (zero) Leave the checkbox checked ON, but pull the slider all the way to the left.
IDLQ at 7 is OK.
Pixel samples at 3 for normal and 4-5 for hi quality. (Going higher brings nothing more.)
MSR set at 1 (one) for draft, 0.5 for normal, and 0.2 (rarely) for hi quality

Bucket size depends on what is in the scene but mostly stays at 32.
Min Displ bounds go up to 0.001

In the Options window all is exactly as I set it here too.
On one condition : That you set crease angle on all "soft" groups to 180° (The free Scenefixer script can do that automatically for you.)

"Separate process" works best on 32 bit machines that are low on RAM.

For performance machines that have lots of RAM, you can leave the renderer internal. (Remove the checkbox)

Happy Posering.

AH, and OK, remove "light emitter"checkmark for the hairs in their properties palette.
