How do you detect CPU Steal Time & over-selling on your cloud VPS?

When renting budget VPS or cloud instances, what’s advertised on paper isn’t always what you get in reality.

Many providers silently over-sell CPU resources, leading to high CPU Steal Time, sluggish disk I/O, or sudden performance degradation during peak hours.

We built CloudWorth (https://getcloudworth.com) to help developers and sysadmins easily benchmark server performance, expose CPU Steal Time, and audit true resource costs with clean, shareable reports.

I'd love to hear from the community:

1. What’s the worst "cloud over-selling" trap you’ve encountered?

2. Which metrics (Steal Time, 4K Random I/O, Network Latency) do you prioritize most when choosing a cloud host?
