It's obvious that any area_light take more time, but you can greatly reduce that by
using adaptive 
in the light deffinition. Start with adaptive 0 and only increase it if you get
artefacts. That way, 
I can use 17*17 or more arays that don't take much more time than 4*4 without
adaptive. Also, you 
can use one area_light for the main light and ordinary secondary light(s).
