Performance optimisation

[Speedauge]

Hello, I've been looking into how Freechess utilizes Stockfish and noticed that the engine only runs on one core. I also found that if you try to perform deep analysis, even with the app running on more cores, the improvement in calculation speed is not significant (45% at most). I personally think that running multiple worker instances and combining the results would be much faster, don't you agree?
If you are interested in the intermediate version that I have adjusted (runs on 4 threads instead of just 1), here it is. (don't forget to change the extension)

Hi @Speedauge ,

To use Stockfish in the browser, the app leverages https://github.com/nmrugg/stockfish.js . It has a multi threaded version that this app uses if your device is compatible. To improve the evaluation performance I believe there is still work to be done on both sides. In https://github.com/nmrugg/stockfish.js to improve its multi threaded version and in this repo to improve how the game analysis runs. If you want to work on this, you can open a PR.
