I wonder if there has been a test to compare connectivity to the major chess websites. Or whether it is easy to run such a test myself if needed.

Here is what I mean to test:

I am mainly playing on two websites (lichess.org and chess.com) and one one of these it frequently feels like I 'lose' seconds. Maybe it is only 1-5 seconds per time, and only once or twice per game, but still it adds up.

I notice this only on one of these sites which makes me suspect it could be server side rather than my personal wifi and such. However, maybe it is a matter of perception, hence my interest in a benchmark or test.

In case it is relevant:

  • In both cases I mostly use the mobile web version from my android phone
  • I am located near Amsterdam
  • Outside the games I do not notice any slowness on the sites

What have I tried?

I ran the ping app on my phone, actually the site where I notice the weird behavior has lower ping time (but neither of them comes close to 1000ms), so I suspect it may not be a general connection issue but rather something that happens when playing games.

    I couldn't find a source right now but afaik premoves differ. In lichess you almost don't lose time on premoves where in chess.com you lose a couple miliseconds even if you premove. But this probably doesn't explain 1-5 seconds delay you mentioned. Edit: There is this reddit post.

    @Minot You lose 0.1 seconds per premove on chess.com (by design). It's nothing to do with connectivity. Commented Nov 15, 2021 at 0:20
  • Do you mean you use the web version from a browser in your phone? In that case consider trying the apps. Commented Nov 15, 2021 at 18:28
  • I will consider the app, but am still curious as to whether there is a way to measure 'in game latency spikes' Commented Nov 21, 2021 at 10:32

    Lichess measures server lag here. This chess.com article is also related, although it refers to players' problems Commented Jan 4, 2022 at 19:56

You can check your ping on lichess.org by going here. For chess.com, you can type /ping in the chat when playing a game by going here.

A trick to check ping on the chess.com app. (Btw, I think it'll be the same on the app and website) Go to New game -> tournaments -> Daily -> Then in the top left you'll get the menu where you can go to Live chess page -> Type /ping in chat.

Edit: The Live server of Chess.com is in the primary data center in California. Following are the approximate ping for the regions on chess.com.

  • 12 ms for US connections
  • 156 ms for European connections
  • 145 ms for Asia-Pacific connections

Lichess's server is located in France. So, the ping would be lower in European countries and higher in other continents.
