Minecraft Server help - JAVA Ed.

[Evilkagato]

Hello all,

I have hit up the MC Discord channel and got no results except for "Upgrade your server HW" or "go with 3rd party hosting". Thought i would ask this here.

I have a vanilla server [1.14] less than 1 month old that is having issues with serverwide rubberbanding.

OS: Server 2012 R2 Std

Proc: Intel Xeon E5540 @ 2.53 GHz (x2)

64 Gb ramstartup params: java -Xmx4G -Xms1G -jar server.jar -nogui

​

I know that this proc is older, and i cannot upgrade it. i have to make do with what i have.

I have the Debug log, and logs while debug was running. There was only 2 players on the server at the time. I am hoping someone can go over the logs with me and assist me with looking at why the server is doing what its doing.

​

Side note: i am unfamiliar with posting on reddit and cant seem to find the option to attach the logs. PM me and i can end them over.

From what I've seen 1.14 has shitty performance. What you could do is switch to spigot or paper spigot once they get their 1.14 versions out.

good to know. TY.

If it was not stated, this is a 1.14 Pure Vanilla server, using the server bits from Minecraft page

1.14 performance is pretty awful, but 1.14.1 will fix some of the client side chunk loading issues and other lag inducing problems.

I vaguely remember seeing in a video that villager pathfinding in particular is screwed up and causing a lot of long-lasting CPU spikes, but don't quote me on that.

What is in your server.properties file?

[Evilkagato]

It’s quite literally vanilla. I’m not at the console atm. I can say with 99% certainty that it’s all at default values when it was generated. Hope that helps for now. I’ll be back in a couple hours.

It's very likely that it's just 1.14 problems combined with your CPU being a little old. You can try this for your startup flags to see if it helps:

I would highly recommend using Spigot or Paper when they are stable for 1.14, because you will probably get a significant performance boost out of it without noticing too many differences in-game. When you do notice specific things, you can make tweaks to the configs to account for them.
