I am a new proxmox user!
I have strange (bad) perfomance results between native fresh windows and VM on proxmox.

Hello, I am using Proxmox VE with Proxmox Backup Server
My backup process is built on an internal 10 gigabit network, I also use ZFS for Proxmox Backup Server with 32GB memory allocation for ARC
Storage capacity 47 TB of which 40TB is occupied
CPU: Intel(R) Xeon(R) CPU E5-2620 v4 @...
Hello Proxmox community,
I hope you all are doing well. I'm writing to seek your advice and guidance on an issue that's been giving me a bit of a challenge. I've just started exploring Proxmox, and while it's been an exciting journey so far, I could really use your collective wisdom on a...
This post is going to be pretty long too long to fit in a single post, but it represents a summary and lessons learned over ~3 weeks of experiments. This post is a half-tutorial and half-RFC so maybe PVE can be improved, as well as a half-tutorial how to actually achieve good results. This...
We are on the point of changing our current IT infrastructure with a small Proxmox cluster of 5 nodes :
Dell Precision R7920
Xeon Gold 5118 or Xeon Silver 4112
128 GB ECC RAM
Data/VM disks (Ceph) on 5x3 16 TB Exos HDD.
System/ISO disk on NVMe SSD via a PCIe adapter. Currently these are...
mir ist aufgefallen das die Performance der Datenspeicher weit unter dem ist was ich erwarten würde. Ich habe 2 Datenspeicher Eingerichtet:
NVME SSD Pool (ZFS Mirror) :
1x SAMSUNG MZVLQ1T0HALB-00000
1x KINGSTON SNV2S1000G
SATA SSD Pool (Ext4 formatiert) :
Verbatim Vi550 S3...
Dear Proxmox users,
Let me briefly explain my situation first.
At the moment I have 2 different servers.
Intel NUC10i5FNK 32GB RAM / 1TB NVME
DIY server Intel XEON 2146G - 64GB RAM / 1TB NVME / 8 WD-RED 4TB.
Both are now running Proxmox 7.3-3
The Intel NUC:
LXC Container Domoticz (DzVents...
Situation: we're running KVM VMs based on Debian/bullseye on Proxmox/PVE with 10GB NICs, but experience packet loss with the virtio-net interfaces under high network traffic situations (RTP/UDP).
This underlying problem also exists on VMware clusters. VMware provides a solution for that: one...
There is a large (3tb) file storage of mixed content on a non-virtual host (text files, archives, videos, etc.). From the documentation it is clear that I can backup as a .pxar or completely as an .img device (after starting it in the console it says that .img.fidx is being created) But from the...
I have incomprehensible results of mariadb benchmark in proxmox. I tested it with sysbench oltp read only benckmark and got this results:
without virtualization 11195.22 transactions per sec
in kvm with scsi disk 8358.25 transactions per sec
and in lxc 7362.25 transactions per sec
we are planning to add a new ceph pull that will be consists of 60 HDDS across 5 servers with 40GB duel network. (one for ceph sync, and one for clients)
in future all the hdd slots will be populated
how far this assumption from the reality:
HDD have a read speed of 100MBs
the data is...
I have a host with 2 sockets (8 pcores/each, 16 cores/each with HT) with Proxmox 5.4.13 installed. Each Processor has 32 GB of RAM memory. I have "NUMA" enabled in all VMs.
When I run numastat, the results are not the expected ones. I get too many numa_miss events:
i have server with hard-raid. The raid has 8 ssd. I made two logical disk. In first disk i use ext4, where is OS-system. On second disk i had test with ext4 and zfs.
When use ext4 i have perfomance 1.3 GB/s. When use zfs and compresion=off then i have 540MB/s. When use zfs and...
Hi all. I wanna ask a few questions:
1. if proxmox nodes in HA cluster must have the same specs (ram, cores). Ive read the documentation for HA but im not sure if it is implied that nodes must have the same specs. i will create a test cluster anyways this week, but would save me time if i have...
Brand new here, did a bit of research on the forum before asking but want to double check before doing something bad 8-)
I've setup a brand new cluster of 5 servers.
Each server has two E5-2697 v3, 256GB of RAM, eight 2TB Hynix SSD as OSD and a pair of 80GB SSD for boot.
It also has six...
I have a slow problem with my VMs (linux / windows) under proxmox, despite the server is efficient server (12 CPU, 64 GB RAM),
I gave the machines a lot RAM and CPU but still the slowness exists, as well as the internet connection is perfect
This is probably common knowledge to many people, but I'm trying to find out what the differences are with the performance of virtual network cards Proxmox supports.
E1000, VirtIO, RTL8139 and vmxnet3
I have a mix of windows & linux clients, and currently using a mix of all these, except for...
im using Proxmox a really long time now, but im still getting confused when "zfs" joins the club. I got a few questions, which i hope some of you can answer. I moved from unRAID in home server use away, because of lesser read and write IO performance, because i plan to nested...
I have an entry level server (Dell PowerEdge T30, 16 Gb RAM, 2 x 1 Tb SATA hard drives) on which I installed Proxmox 5.1 configured with a ZFS RAID1 pool.
I know this is a slow system, but after creating 3 virtual machines the server is terribly slow: continuous high I/O delay and CPU...
