Hi,

 

i have a Server Forge 11.14.3.1464 with 'Installer-Win' installed.

 

I have some laggs and in the Console is the Warning: Can't keep up! Did the system time change, or is the server overloaded?

 

Especially when I go through the Nether Portal.

 

I have start the Server with 8GB RAM and no Mods installed.

 

 

Why is that?

 

 

My system:

 

I7 - 2700K 3,50 Ghz

 

16GB RAM

 

Windows Ultimate 64 bit

Because your server cant keep up. Your computer is to slow in one of the MANY possible things it does that would take time.

These 'cant keep up' messages can't be diagnosed directly.

 

Hello and THX for Help :-)

 

I have now rent a server on Nitrado for test it.

 

And here is the same thing.

 

Here the Log:

Yes, that can be caused by many things, typically not forge as we don't add that much to the tick times {typically we speed them up when forge is used by itself}

This isn't something that can be diagnosed/fixed through logs. You're gunna have to boot up a profiler and learn how to read performance snapshots.
