How to read CPU, RAM, and NVMe when choosing VPS?
Read the numbers for your workload, not marketing: what vCPU, RAM, and NVMe actually affect.
Numbers on a VPS table can look intimidating. In practice, three columns matter most: CPU, RAM, and disk type (NVMe).
CPU (vCPU)
Compute power. More concurrent work (builds, video, heavy queries) needs more cores. For a simple site or API, 2–4 vCPU is often enough.
RAM
Processes and cache running at the same time. If database and app share one machine, RAM runs out fast. Half of “it is slow” complaints are really insufficient RAM.
NVMe disk
Much faster read/write than older HDD or SATA SSD. For WordPress, databases, and logs, NVMe makes a noticeable difference.
Simple sizing guide
- Blog / staging: light CPU + 2–4 GB RAM + NVMe
- Small production API: 2–4 vCPU + 4–8 GB RAM
- E-commerce / multiple services: 4+ vCPU + 8+ GB RAM
On Vexira VPS plans, resources are shown clearly. Look at measurable configuration — not inflated “unlimited” promises.
