Htop and processes question.

Unread post by **kelean** » Fri Jan 11, 2013 5:45 pm

I am running sailtimbocca on a Dell latitude d-800 laptop. I was looking at htop after installing iceweasel to see the difference between it and chromium. Thans when I noticed that there were 28 entries for iceweasel, 17 entries for chromium, and 30 entries for terminal. I have been running linux for years and have never seen this before. Most of the processes have the same stats. I was wondering if anyone else has seen this or just my machine.

Thanks kelean.

in htop, press 'H' and it should look clearer ;)

It's not just you. I don't know what the browsers do with all those processes, but it happens. You can run "pstree" in a terminal to see another representation of what's happening.

Code: Select all

init-+-acpid
     |-conky---5*[{conky}]
     |-cron
     |-cupsd
     |-2*[dbus-daemon]
     |-dbus-launch
     |-dhclient
     |-5*[getty]
     |-hddtemp
     |-login---zsh---startx---xinit-+-Xorg
     |                              `-ratpoison-+-sh---stalonetray
     |                                          `-sh---firefox-bin---19*[{firefox-bin}]
     |-rpc.idmapd
     |-rpc.mountd
     |-rpc.statd
     |-rpcbind
     |-rsyslogd---3*[{rsyslogd}]
     |-tmux-+-zsh-+-pstree
     |      |     `-zsh
     |      `-zsh
     |-udevd---2*[udevd]
     `-urxvtd---2*[tmux]

Firefox has 19 processes.

(edit) and I should note that this output is from a machine running straight Debian sid, before anyone thinks this is something unique to BBQ systems.

Another sicko is consolekit, but IIRC that's (still) a consolekit-bug

Thanks everyone. The H cleaned it up htop mb but the first time I put h not H big difference.

Do not worry about it or do. :) It depends. Chrome/ium has a process for every damn opened tab! Would mean, 50 tabs=50 processes.

^ isn't that part of their sandboxy-security-thingy maybe?

lots of y's in that sentence.

Yep, crash a tab, not a browser. But generally, these are the threads, not processes, shown in htop. Press H and you get the 'old' output that doesn't look frightening :) What counts is in the upper left corner.

Machine is right but that does not prevent Chrome to use more resources than Firefox. Once it was advertised as a lightweight alternative. Ok, I stop to rant, going off-topic.

Oh this (lightweightness of Chromium) was never point of discussion :D Anything else than elinks or xlinks is already blo....

I nearly said the bad word.

Heck, even roaster is ;)

i've gone all stallman and just wget my webpages now,
then read through the HTML... writing directly to port 80 for POST'ing things.
bit quicker than sniffing the TCP/IP packets...
NOT. 8)

sorry am i offtopic?
