You'd rather ask your internet provider about this problem.
Why does this site lag so bad for bullet chess?
Playing bullet chess on this site has become a joke.
It's always had a bit too much lag for me to enjoy the bullet here...
Something like adding 30 seconds to a game is meaningless in long time controls, but in 1|0 it completely changes the game.
They intentionaly lag it if you are not paying for premium service.
That's only useful if they advertise no lag among the premium member benefits.

Playing bullet chess on this site has become a joke. The lag is horrible and happens on about 50% of my games. It makes playing on this site frustrating and futile. Can't you guys fix this?
I heard it was 47.9% of your games]

I would suggest moving your bedroom right next to the chess.com servers.
Look, I don't want to get into all the specific cases where obviously it is not my Internet connect - IT IS LAME SOFTWARE DESIGNED BY CHESS.COM
Someone needs to come up with a new site where bullet can be played and enjoyed without all the bullsheet lag.

I did not renew subscription and now I give up at least 5 seconds in bullet games. Board loads slowly and I cant move my pieces as time ticks off the clock.

Saying that and blaming the site is ridiculous, I have been a free member in chess.com for enough time to say that is not a reasonable statement.
its better to move to the bedroom next door to hte chess.com sservers its actually better
plus i think nobody really plays bullet chess hear
best place to play bullet chess is chess tempo
i mean all of this is good advice..........
but chess.com isnt the place to play bullet chess
sorry chess,com team

I feel chess.com is the best place for bullet despite the fact that my rating here is about 250 points lower than in lichess.
I love the ease with which the pieces move here (especially in the new version). I don't really know how to explain this but I feel that the pieces weigh a lot lighter in chess.com
