Using Benchmark properly: bandwidth beyond latency

Advanced · Updated 2026-04-06 · ~2 min read

As "Latency tests" explained: low ping does not mean fast downloads. Newer Clash for Windows builds add a Benchmark page that downloads a test file through each node to measure true bandwidth — the direct answer to "will video stutter?".

How to use it

  1. Open Benchmark and check the test URL (the default is fine; you can point it at any large file you trust);
  2. Start — nodes are tested one by one and rates shown in MB/s;
  3. Pick your node on the Proxies page based on the results.
