Package: firefox Version: 122.0.1-1 Severity: normal X-Debbugs-Cc: lorenzobertin...@gmail.com
Dear Maintainer, Firefox on debian (both ESR and sid versions) is performing poorly. Here are the results on one of my machines, but it's consistent with all the others: Test: Browserbench Speedometer 2.1 (https://browserbench.org/Speedometer2.1) Gentoo: 290 (+65%) Debian sid with vendor package: 260 (+50%) Debian sid firefox: 175 (-) Debian sid firefox-esr: 160 (-10%) Upon inspection, I think the cause is the optimization flags, including LTO, PGO, O3. Please take this report in consideration, as the performance increase is massive.
