VPS 的 CPU 强不强，看跑分最直接。但别只看一个总分——要分清单核、多核，还要防超售。
常见跑分工具
- Geekbench：最通用，分单核 / 多核两个分数，跨平台可比。
- sysbench：Linux 命令行，算质数测速，快糙但够用。
单核 vs 多核，看哪个？
- 建站、网页、大多数日常应用 → 看单核分数（现代 CPU 单核 Geekbench6 上千算不错）。
- 编译、转码、多线程任务 → 看多核，但 VPS 多为共享核，多核分受邻居影响大。
坑：跑分会”飘”
VPS 跑分受 超售 影响——晚高峰或邻居满载时分数会掉。多跑几次、不同时段测，看稳定性比看峰值更重要。
提醒
记下 CPU 型号（如 EPYC / Xeon 某代），能查规格、对比新旧。性能还要结合 磁盘 一起看。
挑机器趁退款期多测几次；想看在售机型去 库存监控。
Benchmarks are the most straightforward way to gauge a VPS’s CPU strength. But don’t just look at a single total score — understand the difference between single-core and multi-core, and watch out for overselling.
Common Benchmark Tools
- Geekbench: The most widely used tool. Reports separate single-core / multi-core scores that are comparable across platforms.
- sysbench: A Linux command-line tool. Tests prime number computation — quick and rough, but gets the job done.
Single-Core vs. Multi-Core — Which Should You Check?
- Web hosting, websites, and most everyday applications → Focus on the single-core score (a Geekbench 6 single-core score in the thousands is respectable for a modern CPU).
- Compilation, transcoding, and multi-threaded tasks → Look at multi-core scores, but keep in mind that VPS cores are usually shared — multi-core results are heavily influenced by noisy neighbors.
Gotcha: Benchmark Scores Fluctuate
VPS benchmark scores are affected by overselling — scores can drop significantly during evening peak hours or when neighboring VMs are under heavy load. Run tests multiple times at different hours and prioritize consistency over peak results.
Heads Up
Note the CPU model (e.g., EPYC or a specific generation of Xeon) — you can look up the specs and compare across generations. Don’t evaluate CPU performance in isolation; always consider it alongside disk performance.
Make the most of the refund window by running tests several times. Head to Stock Monitor to browse available plans.
