I have noticed that TPS cannot rise to 20 for me and for my friend on the PaperMC 1.12.2 server. It is in the range of 19.6-19.88 all the time. I tried it on a fully clean server, all the same. I didn't change anything or install anything. I tried several times and the result was the same at all times. TPS was not 20 even when no one was on the server. This is not normal, there was no such thing before
What is the problem?
(In this attempt I did not go to the server, but in the others I was there. It didn't change anything)
UPD: Not tested on other cores, only on PaperMC 1.12.2.
UPD2: Also, in timings I noticed that with "TPS Loss 0%", it still shows TPS below 20.
