Excessive cpu use slows computer

hilltownboy · 08-18-2015, 11:22 AM

"top" shows excessive use in ARCH by Xorg and home-name, with additional programs such as browser or libreoffice putting usage over 100 steadily, sometimes freezing the computer. Also a lot of fan and heating.

"top" in Debian WHEEZY, which is also on the same computer, shows usage to be normal, yet WHEEZY is also almost as slow (one minute to bring up iceweasel browser, for example, in which I am writing this slowly).

This slowing began about the time messages showed up in ARCH at first boot. They are not in journalctl so I can only write them from memory:

Code:

[*****](1 of 4) a start job is running for *******(the wired interface)
[*****](2 of 4) a start job is running for wlp16s0
[*****](3 of 4) a start job is running for *******
[*****](4 of 4) a start job is running for *******

The *****'s on the left are flashing red. The ones on the right are notations that I can't remember.

These messages revolve in sequence for a bit, then stop and booting carries on. Can they be a clue to the over usage?

The above is on an hpcompaq6910p. That is regarded as an old machine so I post here because someone may recognize it as a hardware problem.

This indicates that systemd is trying to start a service, but in the end the service fails. This definitely should show up in the journal, however. For a start it would be good to know which services exactly are failing and what you get from

Code:

systemctl status service-name

The four messages that recycle do not show on journalctl. I have examined all 1000+ lines.
Of the two devices that I can identify, here are the references that do show:

Code:

Aug 20 11:19:44 arch systemd[1]: sys-subsystem-net-devices-enp0s25.device: Job sys-subsystem-net-devices-enp0s25.device/start timed out.

Aug 20 11:20:03 arch kernel: e1000e 0000:00:19.0 enp0s25: renamed from eth0

The above is not surprising inasmuch as the wired service cable was not plugged in

Code:

Aug 20 11:21:02 arch kernel: iwl4965 0000:10:00.0 wlp16s0: renamed from wlan0

I'll show service status shortly.

hilltownboy · 08-20-2015, 02:34 PM

I have identified a thiird one of those "a start job is running for ******** device: 8d26da0c

Code:

Aug 20 15:08:01 arch systemd[1]: Activating swap /dev/disk/by-uuid/82b17f58-e5d0-47a9-970a-3aef8d26da0c...

Whether any of this a cause or just a symptom of the unbearably sluggish action of the computer remains to be determined.

Another peculiarity:

Accordig to the specs that machine has GMA X3100 for video. TobiSGD may be able to offer some input on the likely performance of that chip - I had very bad experiences with an earlier GMA.
It may explain poor performance even under Wheezy. As for the swap issue, check that UUID in /etc/fstab. To check if it's really an issue, just comment it out for a while. Also check it isn't specified as a resume target on the boot-loader options.
If you can install inxi, post the output of the following

Code:

inxi -v 4

hilltownboy · 08-21-2015, 10:02 AM

Sorry for this horrible code presentation. Had to get it off PCLinux because inxi is unavailable in WHEEZY and I can't install it in ARCH which is so slow that the wifi connection times out.

The GMA X3100 luckily is not some relabeled PowerVR chip, but a true Intel design. Performance for normal desktop usage should be fine, though this chip is not suited for gaming or serious 3D work.

syg00 · 08-21-2015, 07:30 PM

Yeah, that's pretty ugly - I forgot I have inxi aliased to get rid of the colour highlighting. "inxi -v 4 -c 0" should look better for posting.
So, that actually has an AMD chip using the radeon open source driver - 2-D video performance should be ok. And that Intel iwl4965 should be fine for wifi. Try this on the Arch (and Debian) system so we can compare what drivers you are using

Gentlemen, I have to apologize for dragging you through this whole exercise. I just acquired a new power adapter and now the computer is up to speed. So the trouble was mechanical.

Many thanks for your help, from which I learned a lot.
