| | <p> |
| | OPFS concurrency tester using multiple independent Workers. |
| | Disclaimer: concurrency in OPFS is currently a pain point! |
| | </p> |
| | <p> |
| | URL flags: pass a number of workers using |
| | the <code>workers=N</code> URL flag. Set the time between each |
| | workload with <code>interval=N</code> (milliseconds). Set the |
| | number of worker iterations with <code>iterations=N</code>. |
| | Enable OPFS VFS verbosity with <code>verbose=1-3</code> (output |
| | goes to the dev console). Disable/enable "unlock ASAP" mode |
| | (higher concurrency, lower speed) with <code>unlock-asap=0-1</code>. |
| | </p> |
| | <p>Achtung: if it does not start to do anything within a couple of |
| | seconds, check the dev console: Chrome sometimes fails to load |
| | the wasm module due to "cannot allocate WasmMemory." Closing and |
| | re-opening the tab usually resolves it, but sometimes restarting |
| | the browser is required. |
