Fedora :: CPU Throttling Performance ?
Sep 2, 2009After being forced to rebuild my computer (failed drive) I finally got current and installed F11 (was using F9). I was watching GKrellm last night and noticed something odd. The CPU frequency on my processor (Phenom 9600) was scaled to the slower speed and was rarely being pushed to full speed.
I verified that cpuspeed was in ondemand mode and ran some processor intense tasks (huge image loads, large file cats, large yum installs, etc...). Only when I was able to sustain near 100% load would the system throttle to the full clock speed. It would then drop back to the slower speed very quickly even though the process was still running. As a rough benchmark, I ran these tasks again in performance mode to see what impact this was having. Most of these tasks were taking as much as 40-50% longer to complete in ondemand mode.
Digging further, I found that the default up_threshold in F11 is set to 95%!! This is verified by cating /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold. This means that the system would not throttle to full speed unless a 95% load was sustained for multiple samples (36 miliseconds each by default).
I overrode these settings in /etc/sysconfig/cpuspeed. I change up_threshold to 60 and down_threshold to 30. I am at work right now, so I can't benchmark this change until tonight. I guess I could have just set it to performance mode and left it, but I'd rather save the power when the machine is idle.
Does anyone have any thoughts on why 95% is the default and if there is any problem/benefit to changing this to a much lower value? It seems that anyone with a CPU running SpeedStep or CoolnQuiet would suffer the same severe performance impacts I saw with the default values.
Fedora :: CPU Throttling Not Working On NAS Box ?
Nov 21, 2010I'm trying to get speedstep to work on a intel ss4200 NAS box with a core 2 duo e4600 cpu.
I'm running Fedora 13; Kernel 2.6.34.7-56.SS4200.fc13.x86_64, which is custom with a couple of patches to properly enumerate the hard drive controler.
For some reason the cpu frequency driver it is picking is "p4-clockmod", how do i force the kernel to load the correct driver?

Fedora Installation :: Turning *.iso Into A Bootable CD?
Feb 27, 2009I downloaded the *.iso for a Fedora 10 Live KDE installation. It is currently on my hard drive. I tried burning it to a CD with Roxio using two different methods. The first one was not a bootable method. So I checked the Roxio documentation and burned the image that way. In burning an *.iso to a bootable image on a disc, Roxio asks for three different file types, none of which are *.iso. I selected my *.iso because that was all I had. Then I burned it as a bootable to a CD.
When I tried to boot it, I got a black screen with a message at the top left reading something like there was no operating system available. I thought that was strange, and I do not know what to do.
Fedora :: Turning Off The Plasma Workspace?
Jan 11, 2011I am looking to turn off Plasma Workspace and keep it off! Today I was informed by a family member that their desktop had drastically changed. After investigating this, I had noticed that they were now running what was called Plasma Workspace. I am truly baffled right now as to how this was activated/turned on for only 1 out of 5 users on my computer. None of them are computer savvy, so it would also help me out considerably if I knew how this was turned on without the use of the terminal.

Aug 24, 2010Im trying to maximize my network connectivity. To do this I have begun using the program ethtool. The first thing I did was run
Code:
#ethtool eth0
which informed me Im running 10BaseT mode. So i though, ok, that has to do with the autoneg right?
so I ran:
Code:
# ethtool -s eth0 speed 1000 duplex full autoneg off
[Code]...
LOLz, I got it now, This computer has 2 nics installed! Thats why the link stat was "Link detected: no"
I moded my code to pertain to eth1, the connected port. Eh, anyhow, Im still not sold on this problem being solved, the connection eth1 seems to work fine at 100BaseT/Full but I loose connectivity when trying to use 1000BaseT/Full despite the nic showing it as a supported mode.
Fedora :: FC15 Stop Gnome From Turning Screen Off?
Jun 5, 2011Under Gnome2 you were able to stop the OS from turning off the screen by selecting "never" as the time to turn off the display when the computer was idle. This was found under the screensaver configuration.The screen tool for Gnome3 does not offer "never" as an option. Does anyone know how to stop Fedora 15/Gnome 3 from turning off the display?
View 14 Replies View RelatedSlackware :: How To Disable Cpu Throttling In 13
May 7, 2010I'm trying to install ATLAS which requires disabling cpu throttling. Normally one can do it in the BIOS, while there isn't such an option of my dell inspiron 6400. Actually there is a SpeedStep option in the BIOS, however, you cannot get the highest but the lowest performance by disabling it (dell!!!).
After googled a lot, I found in some distros, there is a /usr/bin/cpufreq-selector through which one can disable throttling. But it doesn't exists in slackware.
I known that by appending kernel option "acpi=off", one can disable the whole acpi and thus the throttling control in slackware, but it seems so dirty.
Anyone known a better way to do it?
ps: With a intel T2050 cpu, i didn't find the directory /sys/devices/system/cpu1, but only the /sys/devices/system/cpu0. Similar case in /etc/acpi. it seems that slackware treats my cpu as a single core one, while it is not.
Networking :: Throttling Bandwidth With Iptables And Tc

Jul 4, 2010I'm going to set up a new linux router for a company, and have to set up bandwidth throttling. They have an unlimited ADSL internet connection which will be shared between 2 businesses, one being them. I will need to set it up so their connection will never be slowed down by the other business. They will both be connected to the same NIC, but will be on different subnets. How would I go about doing this?

View 2 Replies View RelatedNetworking :: ADSL Broadband Throttling File Download ?
Apr 26, 2010I'm not getting file transfers that utilize the max bandwidth of my ADSL broadband. I have a 512 kbps line (I know that's not broadband in most places, but such is the option available to me), and I usually get download speeds of 55-60 kbps. Since the past couple of days, this has dropped to an abysmal 2-3 kbps. So I used [url] to test my download speeds, and they were as expected (i.e. the usual 55-60 kbps). I also used the speed test page of my ISP, and that too, gave the usual results. There has been no throttling from the ISP, as I confirmed from their help desk.
Also, web pages open fine. It's only when I'm downloading a file (Yeah, web pages are also files, but what I mean is compressed archived files; .rar, .tar.?g* et.al.) that I can't get the desired speed. I haven't changed the resolv.conf file, not have I made any other changes that might cause this. I use ppp to dial-up to my ISP, and use the pon and poff scripts that ppp provides. I have a peers file configured for my ISP, which again, I haven't edited.
Software :: Dynamic Bandwidth Throttling For SFTP-uploads?
Aug 20, 2010I am uploading the incremental backups using duply/duplicity using the sftp-module. As the initial upload is pretty big and runs several days (more than 50GB over a 1Mbps-line) I am confronted with the problem that other users in the network experience slowdowns when I upload.
I would like to run a script every n minutes which pings a host in the internet (second hop of the traceroute for example). If the response time is less than a value (150ms), the script throttles the upload for one specific host and protocol. Traffic to the local net (Samba mainly) should be unaffected. I cannot use the QoS of the firewall/router. Also I would like the penalty to be removed if the ping is quicker (loess than 70ms for example) I looked at trickle, and some other out-of-the-box shaping tools but they do not give me the possibility to change the rate while the upload is running.
I would now write a script in perl which uses [URL]some wrapper for iptables combined with some ping module [URL] Also I was trying to get the proof of concept before I start coding: (I haven't verified if this works yet)
sudo tc qdisc add dev eth0 root handle 11: cbq bandwidth 100Mbit avpkt 1000 mpu 64
sudo tc class add dev eth0 parent 11:0 classid 11:1 cbq rate 100kbit allot 1514 prio 1 avpkt 1000 bounded

Ubuntu Servers :: HTTP Throttling - Limit Access To My Web-server
Apr 12, 2010I'm thinking about some ways to limit access to my web-server. It runs Nginx and php in FCGI. The server contains a large amount of information. The data is freely available and no authentication is required but other companies might like to mirror it and use on their own servers.
The requests could be limited on different levels: IP, TCP, HTTP (by nginx) or by the php application. I found some solutions (like Nginx's limit_req_zone directive), but they do not solve the second part of the problem: there's no way to define a whitelist of clients who are allowed to use the data.
I thought about an intellectual firewall that would limit the requests on IP basis, but I'm yet to find such device. Another way was to hack some scripts that would parse the log file every minute and modify the iptables to ban suspicious IPs. It would take days and I doubt this system will survive, say, 1000 requests per second.
Perhaps, some HTTP proxy, like Squid, could do this?
CentOS 5 Hardware :: No Throttling Scalling Speedstep On Xeon Quad-Core
Jun 30, 2009System recognizes that CPU is capable of throttling, but there is no module to govern it. So Xeon always runs at full frequency.This is not convenient as my server is not always in full use, so I would like it to lower power consumption, especially for AC, with frequency scaling enabled.Can you help me is this some bug, misconfiguration in default kernel or guys who writes kernel think that scaling is not necessary for servers processors?
From my analysis so far, I think that the issue lies with the fact that module acpi-cpufreq does not support Xeons and that there is no dedicated module for this processor family (e.g. p4-clockmod) module in the default kernel.
Debian :: Turning OFF The EEE Touchpad
Jan 2, 2011I have posted questions on several Linux forums that asked how I could turn off the touchpad on my new EEE-900A netbook. There is a backstory that is not that relevant, but in a nutshell, I got this tiny low-power computer to be my voice since my speech is impaired. Only the latest Debian has the tools I needed.
After much searching, suggested that I remove the touchpad driver; the command as root: # rmmod psmouse
Did the trick. On the 900A, the protocol that handles the touchpad is the PS/2. Removing the psmouse driver module does not affect my USB mouse, so now I can use my USB mouse and type away with my left hand and bumping into the touchpad doesn't screw things up. In other words: Success. (I am being as explicit as possible so that all search engines will find this.

If i leave it there running, nothing happens, but as soon as i try to run an application (Firefox, Update Manager, etc), the screen turns off and I can't do anything else anymore except reboot.
I was able to apply the latest updates using apt-get update from the terminal (one of the very few apps that doesn't turn the screen off), but can't get rid of the problem, what can i do?
My PC is a Intel Core i5 PC with a Nvidia Gefore 210 graphics card.
I was able to install the proprietary drivers for Nvidea, no change. Both Unity and "Ubuntu Classic" have this issue

Jul 16, 2010I have been using Ubuntu 10.4 trouble free for the last week or so with the exception of one problem. Without warning, my computer shuts off. When I turn the computer back on, it skips the log in page. The turn off is very abrupt and happens without warning. It happened twice when I first installed the OS and has not happened at all until today when it happened twice again. Is this a common issue. It seems like a very odd way for a computer to crash.
