Well, thanks for your help anyways.

It appears that my firewall is blocking the connection somehow, cause when I disable the firewall I get: Pinging 192.168.178.236 with 32 bytes of data: Reply from 192.168.178.236: bytes=32 time<1ms TTL=128 Reply from 192.168.178.236: bytes=32 time<1ms TTL=128 Reply from 192.168.178.236: bytes=32 time<1ms TTL=128 Reply from 192.168.178.236: bytes=32 time<1ms TTL=128 Ping statistics for 192.168.178.236: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms

This is what I get: Pinging 192.168.178.143 with 32 bytes of data: Request timed out. Request timed out. Request timed out. Request timed out. Ping statistics for 192.168.178.143: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

I am 100% sure that both computers are connected using an ethernet cable. How do I run a ping-test between two machines?

I don't have any lag when I play singleplayer. I get the same type of lag with a vanilla server, but it's a little less I believe. Forge 1.12.2 server lags too.

I get one too-long tick message when the server renders the spawn, but afterwards I don't get any messages although the animals keep lagging. My internet has a download speed of 200Mbps and an upload speed of 20.6Mpbs, from what I hear that's pretty fast. Both my gaming pc and the pc which runs the server are connected to the same network with an ethernetcable.

Again, the server is for 2 people only. We are not going to travel 24/7 and we are not going to build huge insane machines. Just a nice survivel with these mods. But this is all pretty inrelevant for now, because my problem is that my server already lags when I don't do anything. I just load the server, I let the world render and I see the animals stuttering like hell. My friend hasn't even joined yet. no offence, but you are telling me commun stuff that I already now, im just wondering if my specs are causing the problem or if I should look for other explenation like incompatible mods. Sorry if my english is bad (i'm Dutch)

You are right, I just want to know if the lag I experience is caused by the specs of my pc or not. So here is a picture of all the mods I want to use on the server. Do you think that an i3-6100 and the aboved mentioned specs would be enough to run these mods without lag?

From the internet I understand that minecraft, so I guess minecraft servers too, use only 1 core. Now im running a 1.10.2 forge server on a separate pc which has a cpu with 2 cores and 3.7Ghz. The pc has a SSD and 8Gb of ram from which I dedicated 4Gb to the server. How much mods should my pc be able to handle without lag? Because I have around 10MB of mods from which Ender io is the biggest (4.9MB) with a total of around 20 mods and im experiencing a lot of lag. The server is for me and my friend only. Im sorry if this is a bit vague, but I believe that my pc is supposed to handle a modded server just fine.

Thanks, I wasn't sure if it worked that way

I am using the lycanitesmobs mod, which is by far the heavyest mod that I use and I want to take some stress from my cpu, but I disabled like 90% of the creatures from the mod (because some of them are ugly as sh*t) Is the mod still heavy even though I don't use everything or becomes the mod way less heavy?

I think that the cpu of my laptop wasn't good enough (4 cores and 2.7Ghz). Im using a differenct desktop pc now with a dual core processor with 3.7Ghz and the lag has decreased. I guess that modded minecraft just needs a pretty beest cpu to run the server. Thx for the help though.

The laptop that I use to run the forge server has 16GB ram and I gave 4GB to the server. I used the following command: @ECHO OFF java -Xms2048M -Xmx4096M -jar forge-1.10.2-12.18.3.2511-universal.jar I have also tried adding: -server -d64 to it but that didn't really help. I'm not using any mods on the server right now, because I already have lag without any mods for some reason. Thx for the reply

I tried running older and newer version of forge and they gave me the same results. I also tried running the server on a different pc and again I got the same lag. I have tried running the server with different .bat files, but that didn't help. My internet is pretty fast: 10 ping, download 200Mbps, upload 20.5Mbps, so that hasn't anything to do with it either. I'm out of options here, does anyone have any suggestion?

Me and a friend wanted to play some minecraft together, so I made a vanilla minecraft server on a seperate laptop. This worked out fine. We had no lag at all and everything worked perfectly. Then we wanted some mods, so I made a Forge Server on the same laptop, but even without mods, the server is lagging. For example when I hit an animal, it just goes in the air, hangs in the air for a second and teleports back down and runs around very laggy and fast. Animals just don't move around smoothly although this wasn't a problem on the vanilla server. I am pretty sure that the specs of my laptop aren't the problem, because the lag doesn't really increase when I add mods. It just looks like standard forge lag. Forge works fine on singleplayer btw. Does anyone have any idea what might causes this standard forge lag on my server?
