Details |
On the attached testcase, I get the following scores:
Firefox: 340ms (Update: 285ms after bug 1851649)
Chrome: 210ms
Safari: 316ms
Matching Chrome's performance would improve Firefox's sp3 score by 0.2%. (This is equivalent to improving a single subtest by 4.1%.)

This was a profile of the reduced testcase.
Here's a profile from Speedometer 3: https://share.firefox.dev/3P2r0xm
It looks quite a bit different.

This avoids uselessly rewinding the parser for single-keyword display
values, and generally makes the code easier to follow.
