server lag with 10% cpu usage and using virtually no ram

can you make a spark report and send it here

and explain server lag, as it clearly doesnt seem to be lagging from the screenshots

whenever I put the tick speed to 100, what my players want it at it lags really bad

Yeah

thats because you are 5x the minecraft speed

That makes the server try to do everything really fast

ok ill send a spark report hold on

if you 5x the speed, itll lag for sure

it ran fine on a 2012 dell optiplex with a 3rd gen i5

same amount of players, doing the Exact same thing? i doubt it

Also was the ram amount different?

less ram

not 2 scenarios can be similar even if the main part the 5X speed was the same

if i type /spark profiler start --timeout 300 it says expected flag at postion 0 but got start instead

what mc version are you running

1.21

The server is purpur 1.21.3

Just a reminder
