After looking at the settings for the Area Light I noticed that samples is set to 150. I changed that to 15 and that reduced render time to a little over 1 minute. I have not looked at why we are getting the circles on the walls yet.
Bidirectional and SPPM are in the very early stages of development and do not work as well as other lighting methods. I use either Photon Mapping or PathTracing for GI. I think that Photon Mapping is usually faster than PathTracing. I used Direct Light most of the time since I did not need GI for my scenes. It is the fastest and I have not focused on rendering outdoor scenes and indoor architectural scenes which look better with GI.
