Why does lichess use up so much CPU? • page 1/2 • General Chess Discussion • lichess.org

I've recently noticed that I've only been running 480 FPS with lichess in the background and opened task manager to find that lichess is take 29 percent of my ryzen CPU. any fixes?

Which URL did you have running in the background? On my 60 FPS setup I'm not seeing this.

@Toadofsky What happens if lichess is restarting but I'm playing a classical game? And how long does restarting take?

I have 200+ tabs but noticed lichess uses the most at 29 percent

Probably cuz you turned on stockfish on lichess.org. It cost me a lot of cpu

specifying the lichess feature set on display, or lichess specific url might help. Also, is that constant? Did you just noticed that, or is it frequent. I am curious. I generally find that the browsers, are increasingly becoming laptop heat threats no matter what url is the starting default....

but i would be curious about lichess contexts where there is no engine at work, in the browser space..

In the past, some internet problems specific to certain IP sets, and lichess server type of packets or something about web sockets being used or not. Not all lichess traffic is handled on the internet facing interfaces the same way.. forum, stream, video, games, what else. they may require different pathways... (specific URL VPN testing, or other VPN might help. there exist free extensions on chrome, that can do that... for diagnostic).

I recall having had some problems at times, attached to my specific IP adress for while, triggering a lot of devtool error console chatter about repeated failed internet requestions.. don'T know if that can take CPU too...

do you get frequent "reconnecting".. that might be a hint... when not at usual lichess front end updating hours....

local engine in browser can be user set, if you are having such thing on (i assume you would know, so just in case, or for testing.. bringing its resources down might have an effect, and have some diagnostic value)..

really out of my jurisdiction here....

lichess does not use cpu unless you have left analysis on i.e stockfish running. it is an event based UI so unless something happens it will not do anything.

#8 Except some periodic ping/pong messages on pages using websockets. But that creates absolutely minimal CPU usage and web traffic.

Right, none of us have seen heavy CPU% except when using Stockfish; perhaps @Proudkid2 can provide more information.

FYI in analysis mode, I think pressing the spacebar key activates Stockfish so it might be possible to accidentally trigger.
