| In order to avoid the CPU frequency spinning down between tests we prefetch all assets before any of the tests start in the browser. | ||
| (In the CLI/shell runner we assume all assets are on disk.) | ||
| Assets are saved in a blob URL so they can be cached on disk. | ||
| This lowers the peak memory footprint of the benchmark to a sustainable level. |

There was a problem hiding this comment.
Is this true in general (i.e., for non-JSC engines)? I.e., does the content behind a blob URL get swapped out of memory to disk before/between workloads? (My assumption so far was that the benefit of the blob URLs is to avoid another network request during the measurement window and to avoid the OS scheduler and CPU dynamic frequency scaling to affect the measurement due to I/O; not that this has a memory benefit.)
