High Load Average

[Kosp]

Hello, so i opened Minecraft server and im getting High Load Average in htop https://i.edostuff.xyz/chrome_WVwaIu6r5v.png i tried with restart but it again go up, please can somebody help me. Will pay!

How many cores does this server have?
Please send a timings report from the Minecraft server also.

16 Cores, i already checked the timings everything is fine.

the load average is fine

Sometimes it go to 5

On multi-processor system, the load is relative to the number of processor cores available. The "100% utilization" mark is 1.00 on a single-core system, 2.00, on a dual-core, 4.00 on a quad-core, etc.

So, as you've stated that your machine has 16 cores, your load avg can technically go up to 16.00 without having any issues. A load avg of 1.00 just means that one core is fully used... that's how minecraft does it. It doesn't really support multithreading unfortunately.

The basic idea behind this is correct, but because it's probably hyperthreaded, you're dealing with 8 physical cores. You can go up to 16 with much of an issue, it really just depends on the specific workload and the linux scheduler...a safe and optimal load average would be between 8 and 12, but can go up to 16 or 17 without any serious performance penalty...20+ would start to introduce lag on your server as a whole.

Also, another side note, the load average is actually based on the I/O scheduler and CPU time, therefore, in some cases, if you are using a platter disk, this could actually cause a bottleneck and result in artificially higher load average. If this ever becomes the case, i'd suggest you to upgrade if you haven't already to a Solid State Disk

Damn, thanks Frank. I'm always glad I can learn some new stuff about linux and such stuff as a whole. I remember having really bad issues on my dedicated machine when it was on ext3 format without any optimizations. My I/O delay was skyrocketing all the time. Once I switched to ext4 with some optimizations my server ran just fine. :,)

Now I'm just sitting at a usual load average of 1.5-2 on an i7-6700 that runs proxmox with like 10 VM's or so.
