基准测试构建器
根据输入计算、校验或分析benchmarkbuilder。
使用步骤
如何使用
- Choose a workload and iteration count.
- Run the benchmark after closing other heavy tabs for a steadier reading.
- Compare elapsed time and operations per second; repeat runs when you need a rough average.
A practical browser benchmark
This tool measures a few representative JavaScript workloads: JSON parsing, string processing, array sorting, and regular-expression matching. It is useful for comparing changes in the same browser and device, not for publishing universal hardware rankings.
Read results with care
Warm-up, browser scheduling, battery mode, background tabs, and device temperature all affect timing. Run several times with the same settings and compare medians when a decision matters.
Private and local
The workload runs in your browser. No benchmark code, result, or device information is uploaded or stored by this page.
常见问题
你可能还想知道
What does operations per second mean?
It is the number of completed iterations divided by the measured elapsed time. A higher value means the selected workload completed more iterations per second in that run.
Can I compare two different devices?
Yes, as a rough comparison, but keep the workload, iteration count, browser, and power conditions the same. Repeat runs because results vary.
Does this benchmark test my whole computer?
No. It measures one selected JavaScript workload on the current page and does not represent graphics, storage, network, or every application.
Does the benchmark send data anywhere?
No. The work and timing are performed locally in your browser.
