performance issues

I have a supermicro h11ssl-i rev 2.0 motherboard (https://www.supermicro.com/en/products/motherboard/H11SSL-i) with 256gb ram and a AMD epyc 7551p CPU. I'm running a pci-passthrough'd boot configuration of windows 11, passing the nvme boot drive and the host CPU to the VM to try to have that...

Hallo zusammen, ich habe einen 13900k im Einsatz und aktuell das Problem, dass ich die Geschwindigkeit der Performance Cores nicht erreiche. Auf dem PVE Host passt das mit den Geschwindigkeiten & das sieht da wie folgt aus: PVE Host Infos: PVE Version: 7.3-4 Kernel Version: 6.1.0-1-pve Wenn...

Ich betreibe 2 Cluster, 1X tolles neues wo alles erwartungsgemäss funktioniert, aber einmal ein günstigeres Setup was in der VM aber eine meiner Meinung nach viel zu schlechte Performance abliefert. Einmal die eingesetzte Hardware und Config: Wir hatten das Synology NAS in Verdacht zur...

Hello, I have old-ish HP ProLiant Microserver Gen8. It has 4x 3.5" bays (currently populated with 2x WD Reds = /dev/sda, /dev/sdb) + 1x old Laptop 2.5" HDD ( I installed Proxmox OS only = /dev/sdc ) My setup is that I have the Proxmox installed on the single 2.5" HDD, where the whole disk was...

Hello, I have 1 SSD 256GB, 2 HDDs each with 1TB. I did a software RAID 1 using only the HDD through proxmox environment. It is ZFS filesystem. Imported a vm (4GB RAM). It uses 12GB of RAM. I wanted to host three websites and considering each has 4GB RAM it looks like the RAM will be used...

I recently migrated my Windows 10 virtual desktop to Windows 11. However, the system has become very unresponsive and feels really sluggish. There is a lot of delay when clicking or typing. I have scoured the Proxmox forums and Google, but so far I haven't found a solution. I ran some...

I've just installed Proxmox on my mini PC. It's weird because the CPU is very low according to Proxmox dashboard - around 1% but RAM is around 18GBs when there's just Windows launched. I've allocated 20GBs of RAM thinking that would be an overkill but it seems it's not. Proxmox host: CPU...

Hallo zusammen, hatte schonmal jemand das gleiche Problem einer schlechten Desktop performance in Windows, wenn man den CPU Type der VM auf "Host" setzt? Die CPU ist ein Intel Xeon W-2245. Wenn ich die CPU der VM auf KVM64 setze, ist die Performance normal.

This has probably been gone over one million times already but time for another round. I did a quick search for the title but didn't find anything that makes much sense for my application in the first 5 threads. I currently have two HP DL380 G7 machines with X5675's 128Gb Ram and consumer drive...

Hi guys, I have installed Proxmox VE on the following hardware: AMD B550 Gaming Mini-ITX AMD ryzen 5700g 32GB RAM Corsair Vengeance PRO SSD Samunsg 980 as OS storage SSD Crucial 1TB as VMs storage Following qm confid ID command for both Linux (ID: 100) and Windows (ID: 101) agent: 0 balloon...

The organization I work for is currently comparing VM overhead between Proxmox 7 and Hyper-V after calls that the Proxmox hosted terminal server had slowdowns. While I did not manage to catch the exact cause of the slowdowns in time in my analysis I did notice the observation that the reported...

I'm running an HP ProLiant DL380 G9 with fully updated firmware and PVE 7, and for some reason, no matter what settings I use, I get a very high disk sec/transfer, which is an indicator of disk latency. The guest, Windows Server 2019, took half an hour to install in Proxmox, and took ages to...

Hi, I'm new to proxmox and started my first backup to a NFS share (TrueNAS Server) via 1G NIC. However, the backup process takes a lot of time, because the network performance mostly idles at a few KiB/s and suddenly jumps to 117MiB/s (max Performance) only for a few seconds. My Proxmox Server...

Hello, I think we have a problem with the disk performance of our Proxmox 7.0 server as a "Windows Server 2012 R2" guest feels sluggish and I guess the values from pveperf should be better. pveperf with running VM (just one on this node): CPU BOGOMIPS: 128001.60 REGEX/SECOND...

Hi, I have a dell r910: 2 x Intel E7-4860 10core 20 thread 256 gig ram Dell H200 HBA controller (factory firmware) 3 x Samsung 4TB SSD. I am getting abysmal disk performance, struggling to get past 70-100MBps Disks are capable of 500+ I would have thought 300+MBps should be achievable. No...

Hi, I've set up a debian VM with the following config: agent: 1 balloon: 2048 boot: order=scsi0;net0 cores: 8 memory: 16384 name: Docker net0: virtio=16:D0:54:56:5D:02,bridge=vmbr0 net1: virtio=02:75:60:E0:2E:17,bridge=vmbr1 numa: 0 onboot: 1 ostype: l26 scsi0...

I'm having severe slowness on a VM with Server 2016. I'm not familiar with Proxmox so any advice would help. The VM is running SQL & RemoteApp. There are about 30 users RDPing into this server and I've thrown all the resources I can at it. The server and the programs on the server just crawl...

Guten Tag Zusammen, aktuell setzen wir ein Proxmox 6.4-4 zusammen mit Linstor 1.7.1 (DRBD 9.0.28) als verteilten Block-Storage für VM Disk-Images über 7 PVE Nodes ein. Uns ist aufgefallen, dass mit steigender Anzahl an Ressourcen und PVE-Nodes die Performance von Linstor erheblich...

Hi there, Disclaimer: I have never had any interaction with a server virtualization management platform and I just wanted a cool software I could use to run multiple VMs, I know nothing about what a ZFS or LVM drive is, I/O delay... etc. I just have experience working with host OS like Ubuntu...
