[0.17.68] Slow multiplayer performance on virutal infrastructure (personal not shared)

[IIPoliII]

Morning dear devs and players around,

I am having a huge issue that's i am trying to find out i have some factorio servers and i am getting really a slow multiplayer, somehow on my other dedicated servers (not at the same place) it works correctly now i know OKAY I KNOW FFS virtual is not recommanded but i am not talking of low end shity virtual i talk about an reserved virtual server hosted by my self.

The "virtual" machine has 8 dedicated cores and 2 virtual cores, 32 gb of ram (can be more but won't be used for now) and 2X 480 gb ssd's in RAID 0, no swap.

It runs on a average 10 gbit/s connection who is really stable at 1 gb/s the ping is about 8 ms at max.

Now i am trying to run a map but it runs perfectly at 60 UPS but i am always waiting on multiplayer here is a preview https://streamable.com/3nojx

Here are the logs as well

Do you have any ideas what is the issue is it the network if yes what in the network?

Thanks Poli

Ps : I am mainly searching for more to debug

This is exactly what a server that can't keep up would look like

The server is a 3.1 - 3.8 GHz Xeon, with DDR3 memory,
And the base looks pretty massive, you are at 6-8 ms update time on your own PC, what are those specs?

I do not really see anything that is a bug, I will move this to technical help

Alright i'll give you more explnations here are the specs of both,

Code: Select all

#Host
https://poli.gg
#Host name
VLPI06
#CPU
10 cores of a Intel® Xeon® E5-2687W v2  (8 DEDICATED)
#RAM
32 Gb DDR3 1866 Mhz ECC (Expandable to 64)
#Disk
2X 460 GB SSD (RAID 0)
#Network
Full 10000 Mbps / 1100 Mo/s upload,download
#DDOS Protecion
25 TBPS (Maybe less or more)
#Subdomain
vlpi06.poli.network

Then my PC :

Code: Select all

Processor: Intel Core X-Series I7-6850K 3.6Ghz 6 Cores 12 Threads 
RAM: Corsair Vengence 2133MHz 4 x 8Go = 32Go DDR4 
System: Microsoft Windows 10 Pro 
Graphics card: Asus ROG GTX 970 (the rtx is in repair)
Motherboard: AsRock X99 Taichi 

Now the problem is that the map is huge yes i confirm but the map is ran on one of my another node who is way more shiter :

Code: Select all

I7-4770
32 GB DDR3 1600 Mhz
2*2 TB 7.2K disks in raid 1
1 gb/s uplink

as you can see it's way worse but i got really no issues i think it's really networking side but i don't know what i can get more than this little clock?

So after a lot of talking with Klonan on discord we founded out it's the virtuisation the problem, i did some more searches and tried to consider factorio as Highly Latency sensitive app in vmware and added a lot of things like INTEL EMT, SRV/IO but still with that it isn't working the problem is not the hardware it's simply VMWare esxi it was tested on 6.7 U2, and i founded out if i turn off nearly all vm's i have less of these issues, but it isn't the solution if once i find a way to optimize it under VMWare i'll put it here !
