I used to host a 1.10 spigot server with a bit less than 1Gb of RAM and the server was running nicely. Recently updated this server in 1.14 vanilla and added 2 more gigs of RAM to my VPS and, well tons of issues:
At startup, world loading does nothing for about 50 seconds and then every message pops in the console.
Like everyone else, 100% constant CPU usage even with only 1 player connected, only 14% when nobody.
Random "Can't keep up..." messages in console.
Random "Moved too quickly..." messages in console.
Extremly poor and unstable TPS.
Generation is just pretty wrecked now, it takes way more longer than before and may result in server crashes...
For me, 1.14 sounded like an exciting update, but I'm really disappointed of the performance gate experienced by servers...
