Details of the issue:

Hello, i have setup a FTB Infinity Evolved 2.3.5 server for me and a few friends but cant work out whats causing this insane server lag.

First my dedicated server specs;

• Intel Core i7 860 Quad Core, Hyperthreaded, 2.8GHz
• 8GB Ram
• Windows 7 64Bit
• FTB server runs from 2x WD Black Sata3 1TB drives in RAID 0
• Java JDK & JRE 8 Update 72 64Bit
• Internet 150 megabit down, 15 megabit up

As you can see from my specs i don't think it's a hardware related issue. Java.exe (server) sits around 20% CPU usage, and around 2GB RAM. Server is using -Xms2048M -Xmx4096M

The map is pretty much brand new with about 20 hours play time over 5 players. No one has really adventured into the modpacks yet. But i am already getting "Server Overloaded" spammed in the console and average tick rates of 200ms+ with just 1 player on the server.

Here is server console log within first 5mins of server being started (1 player):

[05:13:01] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 2966ms behind, skipping 59 tick(s)
[05:13:18] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 14169ms behind, skipping 283 tick(s)
[05:13:31] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 8440ms behind, skipping 168 tick(s)
[05:13:48] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 7375ms behind, skipping 147 tick(s)
[05:14:04] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 4429ms behind, skipping 88 tick(s)
[05:14:35] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 11740ms behind, skipping 234 tick(s)
[05:14:54] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 10703ms behind, skipping 214 tick(s)
[05:15:15] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 5421ms behind, skipping 108 tick(s)
[05:15:34] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 5420ms behind, skipping 108 tick(s)
[05:15:52] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 4684ms behind, skipping 93 tick(s)​

And it slowly gets worse to the point its unplayable (after 20 mins):

[05:20:12] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 5593ms behind, skipping 111 tick(s)
[05:20:27] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 13913ms behind, skipping 278 tick(s)
[05:20:34] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 4385ms behind, skipping 87 tick(s)
[05:20:52] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 4169ms behind, skipping 83 tick(s)
[05:21:23] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 16749ms behind, skipping 334 tick(s)
[05:21:30] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 2778ms behind, skipping 55 tick(s)​

I even get the warning when no one is on server, Average tick says 0.150ms:

[05:39:01] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 2737ms behind, skipping 54 tick(s)​

This is what i use to launch server:

java -Dcom.sun.management.jmxremote -server -Xms2048M -Xmx4096M -XXermSize=256M -XX:+UseParNewGC -XX:+CMSIncrementalPacing -XX:+CMSClassUnloadingEnabled -XXarallelGCThreads=4 -XX:MinHeapFreeRatio=5 -XX:MaxHeapFreeRatio=10 -jar FTBServer-1.7.10-1558.jar
​

I have installed OPIS but am new to the mod and not too sure what i am looking for. I had a little look and nothing seems to be any red flags. Any help would be much appreciated. Thanks ​

I have same problem. Running server on E5-2650v3 (4 cores) 12GB RAM, SSD Caching and with 4 players 1 core is fully 100%, others are just doing nothing there. I have tried updating Java, different java arguments. Currently running with following params: java -server -Xms2G -XmX8G -XX:+AlwaysPreTouch -XX:+UseStringDeduplication -XX:+UseG1GC -XX:MaxGCPauseMillis=200 -XXarallelGCThreads=4 -XX:ConcGCThreads=2.

Server has ton of lag, machines are not even so advanced.. This is very disturbing.
