Maybe I'm spoiled because of the awesome documentation that x265 and x264 had.

Threads in aom is implemented using tiling, so you need tiling active in order for --threads to do anything. --tile-columns and --tile-rows are both in log2 units, and have a value of 0 as default. For example, to get 4 tiles & threads, use --tile-columns=2 --tile-rows=0 --threads=4 or --tile-columns=1 --tile-rows=1 --threads=4.
