https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D260901 Bug ID: 260901 Summary: www/firefox dom.ipc.processCount 8 but maybe more than eight such processes Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Keywords: performance Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: gecko@FreeBSD.org Reporter: grahamperrin@gmail.com Assignee: gecko@FreeBSD.org Flags: maintainer-feedback?(gecko@FreeBSD.org) Created attachment 230657 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D230657&action= =3Dedit Screenshot: an htop view of a thought-provokingly high number of firefox processes dom.ipc.processCount is 8 (the default) however, as far as I can tell: * many more than eight such processes may become apparent=20 in e.g. htop(1) * if excesses are not apparent at start time, after Firefox completes=20 its reopening of previous windows and tabs, then they may become=20 apparent when (for example) I begin to load tabs that were reopened -- maybe only if no favicon is apparent before the click to load. about:support currently shows an isolated web content count:=20 13 =E2=80=93 although I don't know whether this bears any relationship to dom.ipc.processCount =E2=80=93 and htop shows a number greater than 13=20 for firefox processes matching:=20 -isForBrowser At a glance, the number visible in htop _might_ equal the=20 sum of the five types of remote process in about:support.=20 Environment =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D % pkg info -x firefox firefox-95.0.2,2 % pkg -vv | grep -e url -e enabled url : "http://pkg0.pkt.freebsd.org/FreeBSD:14:amd64/latest", enabled : yes, url : "https://alpha.pkgbase.live/current/FreeBSD:14:amd64/latest", enabled : no, url : "file:///usr/local/poudriere/data/packages/main-defau= lt", enabled : yes, % freebsd-version -kru 14.0-CURRENT 14.0-CURRENT 14.0-CURRENT % uname -aKU FreeBSD mowa219-gjp4-8570p-freebsd 14.0-CURRENT FreeBSD 14.0-CURRENT #118 main-n251923-4bae154fe8c: Sat Dec 25 08:03:37 GMT 2021=20=20=20=20 root@mowa219-gjp4-8570p-freebsd:/usr/obj/usr/src/amd64.amd64/sys/GENERIC-NO= DEBUG amd64 1400045 1400045 %=20 Early thoughts =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Ultimately: this might be not a bug, or a bug upstream.=20 For now: after observing symptoms for a few days, my gut feeling is=20 that the behaviours might be specific to the (Tier-3) port to FreeBSD.=20 Certainly: with the port to FreeBSD, it's relatively easy (compared to=20 e.g. Linux) to view the number of firefox processes with utilities=20 such as htop.=20 Qualitatively: sometimes I do feel that recommended performance settings ar= e no longer as effective as they were, say, a few weeks ago. --=20 You are receiving this mail because: You are the assignee for the bug.=
