[opensuse] Resources being sucked...
Not sure if there is an answer to this, but.... I seem to have an issue with the amount of resources being allocated to tasks. Generally my PC runs quite well (Opensuse 13.1 x64, i5, 4 GB ram, KDE, all pretty well up to date), but doing some resource intensive tasks (copying large amounts of data, locally, ie from internal disk to usb2 external disk), basically kills the PC - Can't really be used while the task is ongoing. Any music being played becomes very choppy (off more than on), mouse moves in fits and starts across the screen etc. Basically, I walk away while it's happening. Happens with most resource hungry tasks, including file copies, running VirtualBox, any video operations (rendering, etc) Any ideas?

Check /var/log/messages for any relevant information: use tail -f /var/log/messages in a terminal ... Also, I would check the internal connections and make sure there was no dust/fluff build up then check disks with fsck and smartctl.

Does this only occur with disk I/O, especially when this involves I/O between fast and slow media? What is your graphics card?
Thanks.

Thanks. Regards, Peter Don't believe this is ONLY disk i/o, but shows up noticeably then, as it is a fairly common task... Graphics card is onboard Intel (i5)

I know that when I start trying to move serious data around via USB, even USB3, on any system I pretty much can't do anything. All of my sync & copy work happens at convenient times like breakfast and overnight :-) Something like rsync to minimize data transfer for sync helps a lot, as can some advance planning. If you just gotta move data, though, I bet you're stuck with this behavior as the norm. [And if I'm wrong, I would dearly love to have the better answer, too!] Good luck! :-D -- David T-G See http://justpickone.org/davidtg/email/ See http://justpickone.org/davidtg/tofu.txt

That would be my guess as well. If your machine only has one USB header, you can pretty much swamp it by moving huge amounts of data over it. If you have more than one USB header, try to but the USB drive in a different socket. (front vs back). If its a laptop, you might have a USB nic as well, which is equally disastrous for performance. Sometimes you can put in a fstab line for the usb stick to force SYNC on (which is also refereed to "performance" mode. When you do this, you may (probably) have to mount it manually as root instead of letting the auto-mount work, and you have to unmount it before removal. Forcing Sync mode prevents the default action of mounting in "quick removal" mode (in microsoft terminology). In quick removal mode, the system tries to essentially close the USB device after every write (block) which just compounds the amount of bus traffic. - -- _____________________________________ - ---This space for rent--- -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) iEYEARECAAYFAlLNr7wACgkQv7M3G5+2DLL23ACeMJACRIyueIlMxQzSRSBwvBxr BTAAnRFx8S+B6xM46NEiW9hMAGCCQ8eZ =NB8E -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
