Please bring back PNACL or at least make this as an option

Lichess frequently switches back and forth between PNACL and WASM.
WASM performs 8-12 times slower (at least on my system) and makes the client side analysis useless (even harmfull as it heavily utilizes the system and does close to nothing).

I do not know why lichess make these changes (in the last 2 weeks I have notice the change happened more than 4 times), but if you really want to do this, please give users an option.

I think lichess did this because PNACL was dying. If you actually care about the game analysis, run analysis on your own chess GUI.

With lichess, stockfish 10 takes 30 seconds to get to depth 22, while on my GUI, stockfish 10 takes 15 seconds to get to depth 30+.

I read that thread. From what I understood, PNACL is going to be deprecated soon, so they are testing WASM and as for now it has problems.

Currently on my laptop it still shows PNACL but on my normal machine is shows WASM and that huge machine performs was slower than a low-end laptop.

Lichess implemented a good feature which automatically saves all the evaluations (till move 7). The GUI does not support that.
