[1.10.2] Server "Can't keep up!" messages while in the Nether.


Recommended Posts

If I posted this in the wrong section, please inform me.  I'm still new to the forum.


I run a private server between a few friends and I, and we have a number of mods enabled on our server.  However, upon anyone joining the nether, there's a huge spam of messages in the console about not keeping up, and all entities seem to slow-mo or teleport around.  It only happens in the nether, and we're exploring chunks that have already been loaded.  I'm completely baffled as to why this happens.  I've searched all over the internet to find a solution, but most of the posts seem to be about the vanilla game, with most of the help pointing to plugins that will fix the issue.  I can't seem to find anything to fix it via Forge.


This is the list of mods that I use, if it helps: http://image.prntscr.com/image/aef4238116264d7893ec1edf7cb5366c.png


Processor: Intel® Core i5-3320M CPU @ 2.60GHz

Video Card: Intel® HD Graphics 4000

RAM: 16 GB

Operating System: Microsoft Windows 7 Professional Edition Service Pack 1 (build 7601), 64-bit


My server runs 6GB of RAM, and there's only a max of four people on it at a time.  We lag in the nether when there's only one of us, too.

Can't keep up means that it takes longer then it should to tick everything on the server.

Ticking has nothing to do with RAM.

Its how fast your processor can work.

There isn't a universal fix because there could be a lot of things slowing it down when it comes to mods.

You have to use a profiler, like jprofiler or something to figure out the exact hot spots.

But you could also just try killing mods and seeing if it helps.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.
