Unconfirmed
I have a virtual server with 4 CPU cores. Minecraft server uses 100% of one core, even if no-one is connected. And it doesn't get better – I tried waiting 5 days, still 100%.
I thought the reason might be that I am using a very old world. So I tried creating a new world, but no luck, server still uses 100% of one core.
I tried launching strace on server process – looks like server constantly checks for some unexistent files. Yet I don't know if that's the reason / don't know if it's intended behavior.
strace output:
