https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D266259 Bug ID: 266259 Summary: www/firefox 104: high CPU usage Product: Ports & Packages Version: Latest Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: ports-bugs@FreeBSD.org Reporter: riccardo@torrini.org After updating www/firefox from 103.0.1 to 104.0_2 (also to 104.0_3 and 104.0.1), I noticed the CPU at 100% with top showing 300+% on the first Fir= efox process. This with 103: CPU: 0.4% user, 0.0% nice, 1.0% system, 0.1% interrupt, 98.5% idle Mem: 3077M Active, 5510M Inact, 223M Laundry, 1606M Wired, 1080M Buf, 5328M Free Swap: 4273M Total, 4273M Free PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMM= AND 1632 riccardo 170 20 0 14G 2478M select 0 17:49 0.30% fire= fox [...and 30 more lines with 0.01% or less...] This with 104: 2361 riccardo 147 25 0 13G 1279M select 0 6:13 334.54% firef= ox Also tried with a clean profile (using refresh from within Firefox, removing the entire .mozilla/firefox directory and also with a different user). Returning to 103 stops this problem. I have many windows open/iconized, with many tabs. And I usually have /home= on NFS. I know it. It's bad behavior, even with lockd and statd. But I also tr= ied with a local /home on SSD. Same high CPU usage. Forever (at least for a cou= ple of hours after starting Firefox). No ZFS, only UFS2 both local and remote. Other tests: - madpilot@ compiled a 104.0.1 without LTO, same high CPU usage - madpilot@ saw it on VM under bhyve Firefox configurations: started 103.0.1/104.0.1 with/without: - "Use recommended performance settings" - "Use hardware acceleration when available" The 103 is still usable, the 104 is not. Home desktop: - 13.1-RELEASE-p2 GENERIC amd64 - CPU: Intel(R) Core(TM) i5-7600 CPU @ 3.50GHz (3500.00-MHz K8-class CPU) - 16GB of RAM - video: intel: Driver for Intel(R) HD Graphics - all others pkg updated to latest (all but firefox) --=20 You are receiving this mail because: You are the assignee for the bug.=
