I had unraid running off a HP ML350 G5 2 processor at 2.3ghz and 12cores with 32gb of ram (slow ram like 660mhz)

Either way I was having issues where the server and it would reboot randomly and I couldn't find the problem.

I've been having issue with that server for years and I've put so much money into that I'm just fed up with it.

Time for a simpler server and a quite one too.

 

New system is running a Ryzen 7 2700k 8cores 3.7ghz with x470 Taichi and 32gb pc3200

The VM is  running Ubuntu with 4 cores and 16gb ram

 

We are currently running a 7Days  server

When players would join and play on the old server there was no lag

but now on the new hardware we're experiencing quite a bit of lag.

The VM cores are pinned to threads on the same core

and what I'm noticing is that one thread will hit 100% then jump to another thread and hit 100%

and it will keep hopping around keeping of of the 4 threads at 100% while someone is connecting

and then it settles down.

 

I didn't notice this behavior before on the old system.

 

One thing to note; on the old system I was using onboard video and on this new server I have a really craptastic card I pulled from a hp minitower ati 200x or something. I just needed the card so the system would post. As far as I know the VMs video card is emulated so it should have nothing to do with my hardware one.

 

Any thoughts?

I did notice that IOMMU is disabled on the board, maybe that will help some.

Solved the issue.

Had to turn on the following options in BIOS

IOMMU - enabled

SR-IOV - enabled

 

In addition there are some values that have to be set to enabled putting them on AUTO seems to have no effect. Unfortunately I forgot what those were.

But if you have the option of Enable use that rather than AUTO

 

Everything looks stable and is running smoothly; there is still a peeked  thread when someone joins but only for about 5 seconds then back  down to 2-6%
