Previously, benchpress would use `console.time()` and `console.timeEnd()` to measure the start and end of a test in the performance log. This used to work over navigations - if you called `console.time(id)` then navigated to a different page, calling `console.timeEnd(id)` would still insert an event in the performance log. As of Chrome 65, this is no longer the case. `console.timeEnd(id)` will simply not insert an event in the performance log unless `console.time(id)` was called on the same page. Likewise, using `performance.measure()` does not work if the starting mark was on a different page. This simple workaround uses `performance.mark()` to insert events in the performance log at the start and end of the test. Benchpress looks for '-bpstart' and '-bpend' in the name of the performance mark, and normalizes that to the start and end events expected by PerflogMetric PR Close #24114 |
