Summary Sandbox complexity and performance improvements
Brent Fulgham
Reported 2021-10-04 11:44:53 PDT
The Sandbox team suggested a number of improvements to our sandbox: 1. Minimize regex usage Better to use enumerate individual names than grouping similar names into regexes. This is a performance improvement. 2. Remove duplicate rules 3. Remove 'defined?' checks for the many things that are supported in all WebKit target OSes. These will simplify the rules, and should provide some launch time improvement.

Comment on attachment 440083 [details] Patch Should we also start collecting telemetry for the properties seldom seen? There might be many obsolete properties by now. That falls outside the scope of this patch, however.
