user17898: 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.

user32155: 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.
