It is working fine (or I'm missing something :?: ).

I think Cycles has some accelerator structure for many lights rendering (but DLCS seems to work far better :?: ).

Only in a branch (google summer of code).
It's not merged into master yet as far as I know.

It is Just WONDERFULL To see Such HUGE IMPROVEMENT EVEN FASTER than in ALPHA3.

For Comparison Cycles have to Render For about 8 minute to reach the same quality. 7X speed up compared to Cycles. And have nothing to do with old good sampling strategy method (for these particular render cases)

Cycles 7 min

for proper comparison you have to wait for cycles to merge lighttree(i think that's what their many light sampling acceleration is called).

How to do that. Is there any button to activate this feature in cycles ?

for now you would need the branch that has it implemented. But it would be better to wait until it's in master. Actually I wonder what is taking so long, some tests I've seen looked pretty good. Probably some bugs

Can you post the test scene ?

P.S. anyway, DLSC is useful in scene with many light sources, your seems to have only a sun light and, may be, a sky.
