episode What Virtualization Actually Costs on 2026 Hardware cover

Beskrivelse

When you reflexively install Proxmox on a new Ubuntu server, what performance are you actually trading for those snapshot and rollback capabilities? This episode digs into real benchmark data from a Ryzen 9 7950X running Proxmox 8.3 with a single Ubuntu VM — measuring CPU cycles, memory access, disk I/O, and network throughput. We trace the overhead from VM-exits on Intel and AMD hardware, nested page table walks, virtio driver paths, and the real-world cost of that hypervisor translation layer. The answer: 2-6% depending on workload, with specific numbers for PostgreSQL, Nginx, 7-Zip compression, and NVMe disk operations.
