In the running system, you can get rid of intel_powerclamp: sudo rmmod intel_powerclamp To disable it permanently and suppress loading it altogether, in addition do: cd /etc/modprobe.d sudo su echo install intel_powerclamp /bin/true >intel_powerclamp.conf Then, after a reboot, it wont come back.

Your intuition is correct, there should not be a significant performance problem in the case of an XBMC box. If you think about it, this is almost exactly what the Raspberry Pi does, although technically it uses an SD card rather than a USB drive.

Thanks, your recipe worked great in my MacBook Air 6/2 with Ubuntu 14.10. The only difference was that the offending gpe was gpe66 and not gpe13.

This was caused by SMART data being enabled for the drive in question. Disabling SMART data solved this : sudo smartctl --smart=off /dev/sda Presumably it kept rerunning some kind of internal self-test 30 minutes after the disk spun up and got into a loop; as this was at the hardware layer the rest of the computer was unaware of it going on hence I ...

First you should open the terminal input the command free, then past the results it here. So that we may help you. If you prefer here are some patches not solutions: I would recommend a full clean install. (at the bottom I have explained how to do it) A quick patch not a solution might be installing gnome partition editor. Then resize your partition. The ...

Which size division are you in? I realize this may not be the answer you're looking for here, but for something time critical like standing up within 10 seconds, I would go with an embedded platform. If you have the space / power budget, you should consider sticking something like an arduino on the robot, and programming some open-loop stand-up behaviors. ...

The FSB and RAM speeds will also be slower than newer computers, which will doubtless be adding to the delays. I would say you might be better with a low-overhead distribution such as LUbuntu or LXLE. I have a couple of older laptops that by rights should be fine, but don't seem to cope with the latest distro either. Such is life, unfortunately. You can ...

You probably don't have 3D acceleration, which Ubuntu needs. If 3D acceleration is not found, Ubuntu uses the CPU instead of the GPU to let appear some image on your screen. That's very CPU-intensive, so that's probably why your computer is so slow. Also, the hardware architecture (64 bit vs 32 bit) won't matter. You can try installing the proprietairy ...

Try reducing storage buffer to 4 MB. In /etc/sysctl.conf write: vm.dirty_bytes = 4194304 vm.dirty_background_bytes = 1048576 also maybe reduce writing time to 3 seconds vm.dirty_expire centisecs = 300 vm.dirty_writeback_centisecs = 300 Please comment if this helped or not. Thank you.

All this iso images contains a squashfs image of the file system. Bevor the start it will be copied into the RAM. In most cases this is the slowest part of booting a LiveCD. SquashFS Image file for Ubuntu 14.04.1 64 Bit: 984MB CD/DVD: 21,12 MB/s - Reading speed USB 2.0: 32MB/s - Reading speed It takes 04 minutes and 17 seconds to copy the squashfs file ...

This is one of those applications where you basically start subtracting until you break something and then back off. Like for instance, I don't think your robot is likely using zeroconf which is the avahi daemon, so uninstall it. Do you really need networking? Or better, boot into single user mode (append 1 to kernel cmdline) and then see how many services ...

I am not sure if a server installation of Ubuntu is really the right way to go, because of what you are describing sounds like a job for archlinux or similiar to me. You will need to do a lot of customization on your system, which is when a "take a base system and add anything needed" approach is easier than a "use a full-fledged installation and remove ...

Yeah, it can be normal. Depends on how much management the OS does. The two big tools to impact this are taskset which can direct what CPU a process can use setting the IRQ affinity of your pci devices IRQ affinity is easy to fix. Do some IO, watch /proc/interrupts and if you see MSI-foo all on the same CPU then distribute them. You usually want to ...

You are running by default, the Intel Pstate system in Ubuntu 14.10. To use the older ACPI method, you need to edit the grub file and reboot: Open a terminal alt+ctrl+t and enter the folowing lines: sudo cp /etc/default/grub /etc/default/grub.backup sudo nano /etc/default/grub In the Nano editor, look for the line beginning with ...

You can use iotop. To install, open a terminal and execute the following command: sudo apt-get install iotop To use iotop, open a terminal and type the following command: sudo iotop iotop features real-time display of all disk activity and also displays the command responsible for the activity and the user behind the command just like Resource Monitor. ...

You can use dstat program. To install it, simply execute the command in a terminal sudo apt-get install dstat then using dstat command, you can get a real time CPU/Network/Disk-Activity monitoring view like this mas@mas-laptop:~ > dstat You did not select any stats, using -cdngy by default. ----total-cpu-usage---- -dsk/total- -net/total- ---paging-- ...

There are some ways to configure cron to run a job 30 minutes after startup. Jenkins does that by hashing the function and using H/30 * * * * for example. It could also be a thread sleeping for 30 minutes and spawning a silent cpu killer process. Some ideas there : Did you try htop as root? Some processes may be invisible, I've seen this on Debian ...

That's a 10 year old single core CPU. You're talking about Ubuntu with the Unity desktop? That's designed for modern hardware. It needs the same sort of power that Windows 7 or 8 does. You read all kinds of stuff about Linux being great for old computers, and it is, but the part they don't tell you is that Linux technically is just the kernel. That ...
