performance issues

I understand that LXC has less overhead than a VM, but the difference is so big that I suspect misconfiguration on the VM. Hopefully I can get help to correctly configure a VM for better performance. LXC specs: VM specs: Host specs: Using this fio configuration: [global]...

Hi there, I'm trying to get a VM to run video editing software in MacOS (Resolve and FCPX). I've sorted a host of problems related to disk I/O such that the burst rate looks impossibly high to me, and yet, it still bogs down to completely frozen every few seconds. I thought this was an IO Delay...

Hallo liebe Community, ich habe derzeit das Probleme, dass ich teils bis zu 5 Sekunden Verzögerung auf den VMs habe und finde keinen Fehler. Erst dachten wir, dass es am Netzwerk liegt. Dort allerdings haben wir im Schnitt weniger als 20MB/s an Traffic und die Proxmox Server sind einen 10G...

Hello, I'm building out a VDI model for specialized workstations for a host of reasons, but the primary being malware resilience. I believe if I build a Windows desktop platform underpinned by Proxmox, I'll be able to leverage the PVE for rapid restore of the guest in the case of a Windows...

Hallo Proxmoxer, da ich schon viel gesucht und ausprobiert habe aber noch keine Lösung gefunden habe, bitte ich euch um Hilfe. Ich habe eine VM mit MacOS Ventura erstellt die auch soweit performant läuft. Nur das minimieren von Programm-Fenstern und wieder vergrößern dauert bis zu 10 Sekunden...

On my proxmox server (R7 5700X, 48GB RAM, Proxmox 7.4, Kernel: 6.2.11-2-pve) I have a vm running Arch Linux for gaming with a RX 6700 XT passed through to it. In most games I see performance within margin of error of running bare metal, but some games, most notably Sea of Thieves and Forza...

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...
