No surprise at all. Path tracing works very well with large light sources. And
the largest one possible is usually sky. Most rays terminate very quickly and
the image converges very fast.
The slowest opposite is a unlit room with one single candle behind a corner - or
something similar. It is very random for a ray to actually reach and hit the
candle. Image will be noisy for a long time.
