suggestion: client side analysis using stockfish.js

https://github.com/exoticorn/stockfish-js

this exists, you could save lots of compute time on your servers by using it to run post game analysis in the browser and then upload the result.

This sounds like a very good idea. Don't know why it's not implemented.

This thread is a year old, it has been implemented already! yay

note that it doesn't support many of the variants if any even http://i.imgur.com/oUrcDVa.png

As for uploading the result, it can't be trusted is the main reason, the other is that the javascript version is restricted/limited and therefore not as powerful.

Analysing the games takes a lot of processor time. And it's also quite slow, depending on server load I presume.
I understand investing in new servers was needed because of this.

Moving that processing on the client side would be quite an improvement. I'm sure a solution for trusting the results can be found.

Similarly the processing in the case of games against the computer could be moved client side, if needed to reduce server load.
