Digikam & xorg heavy cpu load

**JoergJaeger** · 24-Oct-2010, 17:39

Hello, i run right now digikam and rebuild my thumbnails. It seems like that this task takes a lot of cpu power and its not digikam itself, rather xorg takes the load.
Is this right? I just wonder.

yester64 says: Hello, i run right now digikam and rebuild my thumbnails. It seems like that this task takes a lot of cpu power and its not digikam itself, rather xorg takes the load.
Is this right? I just wonder.

As far as I know yester64, it would never be normal for Xorg to be using 97% of your CPU time. That is just crazy, but we need to know more about what you are doing. I see that digikam is a very distant second at 3%. I would ask a lot more about your computer hardware and software setup to be able to say more. What openSUSE version, 32/64 bit, KDE version, computer brand/model, memory total/free, hard disk size/free, video, sound and anything else that might be important. You know the drill cause you have seen it enough around here. Do you have this happen with anything else or is digikam the only cause?

Thank You,

Not only cpu power, but your 4GB of memory is almost all in use. That doesn't look good. Less than half of my 3GB is now being used with digikam, firefox, xorg loaded.

**JoergJaeger** · 24-Oct-2010, 18:46

The weird thing is, that in the beginning it runs smooth but after 15 or 17% it gets sluggish. I did not do a whole scan, just a for the missing thumbnails.

Can it be that i have a bottleneck somewhere? If i check with KDE's info it showed xorg with around 50%. It looked like that there was something filling up (database?) and then it went slow to slow... very strange.
Now i know that i have a lot of images that are scanned, but should that matter?

So you did not post any details about your software setup there yester64, but after further review of your original post, it looks like you are running out of memory.

Code:

Mem:   4055392k total,  4008052k used,    47340k free,   255244k buffers
Swap:  4193276k total,     1276k used,  4192000k free,  2311168k cached

So, before you even run Digikam do you know if you might have loaded Tracker (Seach for tracker using YaST / Software Management) OR if you are using KDE's Nepomuk by chance? Either program can potentially use up all of your memory, depending on how they are configured.

So, if you are running low on memory, then add one more disk intensive action like scanning for pictures and perhaps the wheels fall off of openSUSE & KDE?

Thank You,

Swap:  4193276k total,     1276k used,  4192000k free,  2311168k cached

So, before you even run Digikam do you know if you might have loaded Tracker (Seach for tracker using YaST / Software Management) OR if you are using KDE's Nepomuk by chance? Either program can potentially use up all of your memory, depending on how they are configured.

So, if you are running low on memory, then add one more disk intensive action like scanning for pictures and perhaps the wheels fall off of openSUSE & KDE?

Thank You,

Not installed. Looks like its for database.

Did you not read my post? Of course he is running out of memory. No need for "further review". That's just repitition!

It could be a memory leak. Hence the buildup: "The weird thing is, that in the beginning it runs smooth but after 15 or 17% it gets sluggish."
