Thanks for the reply Darrel. I changed the settings and it did help some. Attached are two simple drawings made new in each program. 18 platinum with polished brass on the cylinder and the sphere is just black with no material applied. 22 platinum the cylinder is redsdk polished brass and again just black no material sphere. In 18 the quality render takes 1-2 seconds from wire frame, in 22 it took 48 seconds ray trace standard and 77 seconds ray trace fine (similar with global illumination). After changing settings to your suggestions it took 11 seconds in standard and 51 seconds in fine. An improvement but that is a lot slower then 18 which also had a nicer finish which like I have mentioned is likely just figuring out the redsdk settings. These are both with default lighting settings.
