| 32 | <br> |
| 33 | <br> |
| 34 | |

| 36 | <pre> |
| 37 | d8 --prof your-file.js |
| 38 | </pre> |
| 39 | |
| 40 | Then process the file (this resolves C++ symbols and produces |
| 41 | a JSON file with the profile data): |
| 42 | |
| 43 | <pre> |
| 44 | <v8-dir>/tools/linux-tick-processor --preprocess v8.log > v8.json |
| 45 | </pre> |
| 46 | |
| 47 | To view the profile, click the <i>Choose file</i> button above and choose |
| 48 | the file in the dialog box. |
