https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=260901 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: email@example.com Assignee: gecko@FreeBSD.org Flags: maintainer-feedback?(gecko@FreeBSD.org) Created attachment 230657 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=230657&action=edit 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 in e.g. htop(1) * if excesses are not apparent at start time, after Firefox completes its reopening of previous windows and tabs, then they may become 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: 13 – although I don't know whether this bears any relationship to dom.ipc.processCount – and htop shows a number greater than 13 for firefox processes matching: -isForBrowser At a glance, the number visible in htop _might_ equal the sum of the five types of remote process in about:support.

For now: after observing symptoms for a few days, my gut feeling is that the behaviours might be specific to the (Tier-3) port to FreeBSD. Certainly: with the port to FreeBSD, it's relatively easy (compared to e.g. Linux) to view the number of firefox processes with utilities such as htop. Qualitatively: sometimes I do feel that recommended performance settings are no longer as effective as they were, say, a few weeks ago. -- You are receiving this mail because: You are the assignee for the bug.
