performance

Saw a mini PC with a Ryzen 7 3700U. I know that this processor is outdated, may this device consider small power consumption but big processing power? My main purpose is to install OpenWRT on the Proxmox as a Internet router. May simply learn docker, container and linux, use the virtual machine...

Hello all, We have a following Proxmox setup: One storage server, HP DL380P G8, CPU Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz, 32GB RAM Storage Pool assembled on 8xSSD, Samsung SSD 870 QVO 1TB, which are put into the four mirrors with 2 drives each, and then mirrors are setup into the stripe...

Machine is a reused gaming PC R5 1600 16GB 2133 RAM Gigabyte AB350 Gaming 3 Proxmox installed on a 120GB SATA SSD Disks in questions are two WD Red Plus 4TB (yes CMR variants, wd40efzx) running in Mirror mode. https://i.imgur.com/zlCw5HF.png Drives are assigned to a Ubuntu server VM whose...

Hello, I'm not sure if this is normal. PVE is reporting almost 50% RAM usage (out of 56 GiB) while all I have running are 2 lxc containers which combined have under 1 GB of RAM allocated. I do have a Windows 10 VM set up but it is stopped and its RAM is from 8 to 24 GB. When I use top to see...

Hello, I've found a few threads about similiar problem but none of them have a solution. We have a 3 node cluster with multipathed iSCSI storage using IBM Storwize SAN. In Proxmox 6.4 which we use, there is a shared LVM created which stores VMs on all nodes. We didn't notice any performance...

Hello all, We're looking for Best Practices regarding setting IOPS and Throughput limits on "Hard Disks" in proxmox. There's obviously limit and brust settings under Advanced on a given disk. Questions we have: Is there a way to see, from the Host level, the current IOPS/Throughput a...

Hello. I assembled mdadm raid0 from two Samsung 970 Evo plus NVMe SSDs, created an LVM VG on it and gave the thick LV as a virtual machine disk based on Centos8. On a hypervisor, this RAID delivers about 7GB/s read performance. When I test inside the guest OS with: fio --readonly --name=onessd...

Hi All, Hoping to gain a better understanding of why I'm seeing a difference in performance running the same fio command in different contexts. A little background, my pool originally consisted contained 4 vdevs, each with 2x 3TB. However due to a failing disk on mirror-3 and wanting to...

Hello everybody. What is the best processor configuration (VM performance) for these specifications? I'm using "host", I intend to create a replication with the same specifications in the future. Should I change the processor of each VM?

Hello there, I'm currently working with resolving some performance issues on a Proxmox installation. There is a ZFS array on the network which is hosting the VMs, and the behavior is strange. Currently, the server is hosting 3 Windows 10 VMs with the configuration shown in the attached image...

Hi All, I installed proxmox (using ext4 filesystem) on a 5212MB SATA SSD (used consumer-grade Sandisk SD8SB8U512G1001) to evaluate it. I run some benchmarks using fio, to get an idea of how fast it is. Before installing proxmox, I benchmarked the disk with PassMark's Performance Test on Win1o...

I'm having really poor performance when copying data from one physical USB-C disk to another physical USB-A disk plugged into the same Proxmox VE-system. The rsync below is only at 0.85kB/s. Filesystems are both ext4 and the disks are created as VM-disks: directories and raw. In the VM doing...

Hi, I want to use the best performance configuration. I need help to find out which VM configuration is the best for me. The best performance means the drivers use low CPU time. I will use local storage with a separate disk. Which file system is best for sata qcow2 virtual machines? All VMs...

I'd like to setup proxmox 7 to be as fast as it can possibly be with the hardware I have and that I am considering to get; EDIT: (this will be for non critical, non server related workloads) Edit 2: I would like to have a dedicated VM to pass GPU's to so that I can donate to the folding at home...

Hi, I've noticed that the CPU performance of the VMs is well below what it should be. I have a newer one that has a CPU with less performance than this newer one, and the VM on geekbench delivers what it should deliver. A VPS on the newer one has less performance than the previous generation...

Since updating to Proxmox version 7, we have not been able to backup a single VM (Production affected) The issue is that VZDUMP slows down and VM's on the Proxmox nodes become unresponsive. I was able to get 450MB transfer using rsync to the VM locally to test access to the vm drives which go...

Hallo Leute, ich bin komplett neu in die Proxmox Materie eingetaucht. Bisher hatte ich einen Home Server mit Hyper V am laufen und bin nun auf Proxmox umgestiegen. Da ich nur einen kleinen 2HE Mini Server habe, habe ich 4 Nvmes verwendet (WD Black SN750 mit 500 GB PCIe 3.0x4) und auf diesen...

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...

We have a large volume that we need to backup which contains 100.000.000 files, with a ∆ / day of about 50.000 files (400GB). For the time being this file system is mounted directly in PBS using fuse kernel driver with mount -t ceph ip.srv.1,ip.srv.2,ip.srv.3,ipsrv.4:/ /mnt/mycephfs -o...

Hi, I'm fairly new to Proxmox and Linux, so please excuse my noobiness. Objective Trying to move away from a MacMini hosting SMB shares (the crooked Apple way), TimeMachines and running some Debian/Windows VMs via Virtualbox for Homelab stuff. Moving towards a "real" (home) server with Debian...
