How much CPU and RAM does a VPS need?
Start with a realistic baseline, monitor it and resize. Buying a large idle server is not reliability; keeping measurable headroom is.
Useful baselines
| Workload | vCPU | RAM |
|---|---|---|
| VPN, proxy or small bot | 1 | 1–2 GB |
| WordPress or small API | 2 | 2–4 GB |
| Shop plus database | 2–4 | 4–8 GB |
| Build worker or busy database | 4+ | 8+ GB |
Know what to upgrade
- Sustained CPU saturation or throttling suggests more/faster cores.
- Swap activity and out-of-memory kills suggest more RAM.
- High I/O wait points to storage before CPU.
- Slow responses with low server load may be network or application latency.
Leave 20–30% normal headroom and test at expected peak load. Vertical scaling is convenient, but backups and a rollback plan are still essential.
Match plans to your baselineSet CPU and RAM filters, then compare price.
