Server Can't keep up! Did the system time change

You didn’t pre-generate before, do you have this kind of delay?

Before I pregenerated, I did have that same delays. After world generation, I have much less lag!
(I still have a bit of lag, but not as much)

But is there any other solution? I don’t think that’s the problem. When I don’t load the block, it also delays.

I’ve been using spigot for a long time and I’ve never had this problem!

Is this a common disease?

If there is a delay when the block is actually loaded, I can understand the delay. But the server has no players, and I stay there with spawn, and there’s a delay, which I don’t understand!
Sorry, I can’t speak English. I use the translation software. So I hope you understand!

Well that’s usually the solution. What are your java arguments?

java -Xms6G -Xmx12G -Dfile.encoding=UTF-8 -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -XX:MaxGCPauseMillis=100 -XX:+DisableExplicitGC -XX:TargetSurvivorRatio=90 -XX:G1NewSizePercent=35 -XX:G1MaxNewSizePercent=60 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=50 -XX:+AggressiveOpts -XX:+AlwaysPreTouch -jar forge-1.12.2-14.23.4.2705-universal.jar

I tried the optimization parameters in BBS, but they didn’t work.

Can you send me a copy of your server configuration for my reference?

I need a sponge global.conf

global.conf configuration

My global.conf is just the default, I never changed it.
