the site is unusable for bullet chess

the adds could run and completely stop the browser. can't move pieces. also, if the adds are not killed, which is in case of Firefox the ram gets high jacked and runs up to the limit, 90+%

Recently I've been having freeze problems, just as of about 4 days ago. Usually at the end of my games when the ad is generating. Then the subsequent game when I got 'New' has some initial freeze. I tried clearing cache, cookies, restarting browser and restarting machine but after a few games the freezes come back.

I'm not a techie, but I've also noticed that the game is freezing when I play bullet.  The lag is getting worse and worse, taking the fun out of the game.

Having the same issue

agreed. allowing unverified javascript in ads? 2GB RAM and 100%+ CPU in a chess.com browser tab? are they mining freaking bitcoin? unusable.

Anyone else noticed their clocks just dropping 5 to 15 seconds just in the middle of a game even though you as the user is moving at a normal second or less?  Super frustrating to play on it.  Not sure why.  My internet is fast.  It is obvious there are places in the world that are unaffected by this and other places that are. I've tried different machines, tried different internet connections.  There is always an issue with how the move translates in time to the server and it's way off.  Maybe remove the ability to premove 10 moves ahead and just do it like regular chess where you can move only 1 move at a time...maybe the server is being overwhelmed with calls?

Internet traffic in general is up globally and that includes the US. A lot of people are working from home, where before they weren't and much of their day-to-day traffic was internal to the company they worked at. Add to that the site is experiencing increased loads due to more people not being at school/work.

You might get a little benefit by experimenting with the Live chess connection options, but until things normalize, things are very likely to continue in a similar vein for many members.

I mean it's hilarious.  I'm crushing people and then the clock will run like 8 or 10 seconds and I'm waiting...and then lose on time.  I'm rated over 2000 on other sites and can't crack 1600 on this site cause of this issue. All time based losses, of me trying to deal with the handicap chess.com imposes...it's laughable.  Get some new coders.

The site only allows a certain amount of lag; other sites handle lag much differently, so it isn't really an issue of coding but philosophy of how to handle lag. Add to that, increased overall traffic on the internet and the influence of advertisements here, the comparisons aren't really good between sites.

That said, other sites also start players at a different rating and pools of players are different. You shouldn't expect your ratings to be the same and from what I've read, ratings are higher in general at least one other well known site.

Thanks for the info Martin, that is helpful to know. 

Is there any truth to hvenki's comments? If we upgrade will we see less lag in bullet games? I find it hard to believe. 

You won't have advertisements, so that can certainly impact potential lag.

You actually will see less lag, especially depending on the strength of your computer. Everything your computer does takes CPU power. Even ads (unfortunately), though we try to minimize it as much as possible. So, your computer will have more resources to devote to the game if there are no ads. A Gold membership is 8 cents per day and has no ads, more puzzles, etc. Or, frankly, if you can't afford to support the site with that kind of investment, and hate the ads, you can use an ad blocker I guess  

I wonder if the unstable nature of bullet has to do with the number of premoves one can send to the server in a fraction of a second?  

The time I see per move is completely wrong...looking back over games.  

For instance one could make close to 10 moves before someone has even moved a piece. This is the true problem with bullet.  In no way does this mimic real chess.  Maybe limiting blitz and bullet to one premove would help the server response from being overloaded.

I wouldn't imagine premoves put very much load on the server process. It is a very small amount of data stuck into a move queue.

Give me a break it has nothing to do with internet traffic its the protocol they use to determine your connectivity ... its just too sensitive.  I lose connection on a 75Mb internet over ethernet ... I lose connection so much on mobile its russian roulette to play on a mobile.

Unless more people complain about this nothing will change ... I wont renew subcription thats for sure.

UBlock Origin  .....   get it and no ads.

@stevebez 100% - I'm running about 85mb and will even have this happen to start a game.  How exactly am I supposed to play?  I literally lose almost every game because of this.  I feel like I pretty much have to win in 30 seconds or mate....it's a complete joke.

Considering what this site charges and having to do with these kinds of problems.......makes [another site -- MOD] very attractive.   I play there regularly and here only once in a while.

Perfect example: [another site -- MOD] allows 1 premove.  Just my gut feeling that this is where the problem lies.
