Mike, how did you calculate how many files are opened by firefox? I just added up all the entries in /proc/<pid>/fd for firefox and its children processes and I "only" got 1881.
2256004 seems like an astonishing number. Can you clarify this?
Hi Jim,
"lsof -n | grep firefox | wc -l" includes things like memory mapped libraries.
"ps ax | grep firefox | wc -l" currently yields 78 firefox processes but "ps -eLf | grep firefox | wc -l" yields 2319 firefox threads.
(This of course is nowhere near bulletproof but it'll do for now.)
I probably have a couple hundred tabs open, across 23 firefox windows.
Thanks Mike.
I have three different firefox profiles running, and I'd guess over 100 tabs (more than I feel like counting right now).
What are you guys doing with that many tabs open ???
For lsof -n | grep firefox | wc -l I get 882961 (which is a lot more than I would have guessed before seeing your message, but not up in the same range as you).
(Incidentally, I see that that the above grep catches lots of lines like Socket 621 ... /usr/lib64/firefox/libsoftokn3.so and I wonder whether the above grep double-counts some things. But maybe that isn't a big deal anyway.)
FYI, on my system right now ps ax | grep firefox | wc -l gives 100, and ps -eLf | grep firefox | wc -l gives 3105.
It is interesting (to me) that you have fewer threads, and yet about 2.55 times as many files opened.
For comparison, for a chromium instance with 22 tabs lsof reports 75422 files, and for 9 (collectively) urxvt terminals (with some perl extensions) lsof reports 732 open files. Evidently the web browser programmers are experts at writing software that uses lots of files. ;-)
