high CPU load. Normally not high at all..

@jhmiller

Some ideas....

Users running deluge, couch potato, sickbeard not system users.

When i see high cpu it usually is caused by issues with the home directory. I am finding that home directory in most cases should be set to working directory of the application. Is anyone else experiencing high cpu with these applications? With Emby home directory could not be set in postinst because the home directory did not exist yet. The home directory (working directory) was created on first run of the application. Home directory had to be set in mkconf with usermod -d. This is something that should be looked into with each of these applications.

a bit less code to find arch... no uname.

if arch | grep x86_64 >/dev/null 2>&1; then
        LIBS_LINK="${LIBS_AMD64}"
        echo "cpu 64 bit..."
    elif arch | grep 86 >/dev/null 2>&1; then
        LIBS_LINK="${LIBS_I386}"
        echo "cpu 32 bit..."
    elif arch | grep armv7l >/dev/null 2>&1; then
        LIBS_LINK="${LIBS_ARMHF}"
        echo "cpu armhf..."
    else
        echo "cpu architecture not supported.  exiting..."
        exit 0
    fi

As with all the plugins I started I just tried what I could at the time, if it worked I left it, you or any one else is more then welcome to make changes where you think it is needed.

I looked over them quickly Miller. I just pointed out some ideas. I had issue with Emby on the home directory and I start to think this is really important on other applications. It is ez to test manually by changing the home directory on a given app giving high cpu. When I fixed this on Emby cpu usage went down over 2/3rds. If you find someone else on github that has done work on same app you can sometimes see if they have done anything with the home directory too.

You are already doing some things different, like system user. So some of the things are just improving old work.

I think the big question is are other people experiencing high cpu on these apps??? If so definitely look at home directory as possible cause.

Never had any issues with high CPU usage with any of the apps I use, admittedly I don't use deluge but the rest are almost always low when ever I check them. My highest item are plex (understandable) and my newsgroup indexer/server (does a lot of work)

The 3 apps use python. If one app has issue if probably will effect the other using python. I would try to check Deluge first. If you know where it has working directory I would have this guy change his home to it. Or check for other projects on github. Maybe you find answer there.

If I were him I would disable those 3 and try running each one alone with the others off. Try to figure out if it is just one or maybe more that is causing the problem.

I looked some more a Deluge. It's home should be here:

/home/deluged/.config/deluge

UMASK=0 # Change this to 0 if running deluged as its own user
PKGNAME=deluge-daemon
SCRIPTNAME=/etc/init.d/$PKGNAME

I will look at it tomorrow as its getting late (early)

I think your suggestion above about running the apps 1 at a time to see if 1 of them is effecting the others is a good one and the best place to start.

It is hard. You really have to install them to check that everything is setting up right. You need another app to test this too.

It was not clear install was finished:

upgrades to 2 packages

Setting up libtorrent-rasterbar7 (0.16.18-1~bpo70+1) ...
Setting up python-libtorrent (0.16.18-1~bpo70+1) ...

Home directory:

root@stoneburnervm:/# cat /etc/passwd | grep deluge-daemon
deluge-daemon:x:1003:100::/home/deluge-daemon:/usr/sbin/nologin

root@stoneburnervm:/# id deluge-daemon
uid=1003(deluge-daemon) gid=100(users) groups=100(users)

Very low cpu... but not connected

Looks pretty normal. Home directory is ok and config files there.

I think it is user error. He probably has a permissions problem. Deluge is working fine.

If you are getting high cpu lower your max download rate. Transmission is using less cpu at same download bandwidth. I have both set to max download at 1024 kb/s in the picture.

There is a discussion on the forums for Deluge regarding high cpu. This problem has been going on for some time with Deluge.
