It might be assumed that it is the double sized net, but I don't think so.
I am getting about 60M NPS, where I used to get about 90M, which would account for less than a ply.
I am seeing lots of very slow searches just to reach 30 ply.

I wonder what will happen to SF in long time control with powerful hardware matches when it is out-searched by 15 plies.

Try searching these with the latest abrok stockfish and a version about a month older:
Code:

It is possible that I just hit a slow patch while I was watching. They seem to be going a little better now.
I am analyzing positions from games by Baron Tassilo von Heydebrand und der Lasa.

Progress has been not much lately. As for a wild guess, they moved to a bigger net because the 20Mb net is saturated. I hope my guess is wrong.
