I've installed Slackware 13.0 (32bit) on my PC to use it mostly as router + small server. And there is a problem with system load. Whenever there is some network activity it loads my cpu. Even if some other PC from my home network downloads smth from the internet through the Slackware.
Top shows "11.7%us, 41.3%sy, 0.0%ni, 0.0%id, 0.0%wa, 12.7%hi, 34.3%si, 0.0%st" (notice the 34.3%si). And ksoftirqd/0 process takes more then 20% cpu.
First I thought that this is a kernel issue. I've tried building my own kernel. It didn't help. I've used a liveCD(actually it was archlinux install cd) to boot and it had no problems. But when I tried loading Slackware with liveCD's kernel the problem remained. So I'm guessing it's not the kernel.
I've tried clearing all iptables rules and disabling routing. I copied udev rules and modprobe.d from the liveCD. I disabled ipv6. I've prevented rc.inet1 from loading and used ifconfig to manually setup the network. None of
Slow performance due to high rate of software interrupts in application
location: linuxquestions.com - date: May 14, 2009
I have an a client/server based multi-threaded application. The server's CPU consumption goes up-and-down from 0.1% to 15% although everything remains same. In 'top' output, I see that all things remain same except "%si" which is in complete sync with CPU utilization.
Is there a way to get to know which software interrupts are making up this percentage of "si".
I found "/proc/softirq" but I could not found a rpm for that.
Need help determining if %SI(software interrupts) are too high

The organization I work for uses SCOM(Microsoft Systems Center Operations Manager) for Data Center Management/alerting. Since the client was installed on our Linux servers we have been getting messages from SCOM stating "DPC Time Percentage is too high". This is happening on all our MySQL cluster servers. From researching it appears that this message relates to software interrupts.
From running top or mpstat I can see the %SI for processor 7 is frequently over 20%.
Why software interrupts can sleep while it is not allowed in hardware interrupts?

Why we can sleep in software interrupt case while it is not allowed in case of hardware interrupt?
e.g. System calls can sleep while ISR cannot sleep.
Fedora "software sources" vs. Ubuntu "software repositories"
location: linuxquestions.com - date: January 23, 2011
I am back to the "Red" side at the moment installing a Fedora 14 virtual machine in VMWare. I have not used Fedora since about 3 or 4. I want to install Gnome Commander. In Ubuntu I check the repository "...ubuntu lucid partner" and I can find Gnome Commander within the Synaptic Package Manager tool.
In Fedora 14 I do not find Gnome Commander listed in the Add/Remove Software app. I find something which looks similar to the Ubuntu Repositories functionality in System; Administration; Software Sources. However, these all appear to be Fedora specific.
So I did a search and determined that Gnome Commander was available via yum.
Apple software vs Windows software on Linux...
location: linuxquestions.com - date: September 25, 2003
First, is it possible to install Apple software on Linux? If so, since Apple's OSX is based off of Linux(correct?), would it run any more smoothly than Windows software? I'm just thinking, perhaps for things like WarCraft 3 or maybe even Photoshop, the programs would run more nativly than Windows software...
Running compiled software of CentOS on Ubuntu
location: linuxquestions.com - date: January 26, 2013
I wanted to know if there is any issue in what I am doing.
I compiled the latest version of Python 2.7.3 on CentOS 5.9 and its running properly.
I compiled it at :
If I copy this folder to a ubuntu server as well, it works without any errors.
I have been trying to figure out what is the issue in this ?
Could it be unstable ?

Joli OS 1.2 Software Channel
location: ubuntuforums.com - date: April 24, 2011
I looked around for the Joli OS Forums, but they don't seem to have that but they do have a support page. I was wondering if anyone on here has used Joli OS 1.2 on their system. If you have can you help me with one thing. I know Joli OS is basically based on Ubuntu 10.04, just a cloud page for a desktop. Its settings are similar to all with Ubuntu. So for my question, I'm trying to install Xara Xtreme on here but when I load the .deb file it says the same version is already in the software channel. I'm not to sure if it means synaptic or something else such as the main add button (The green plus icon to the left) for adding apps mainly just shortcuts to web pages.
Here's a screenshot showing what its telling me.
"Add button" Don't know where to find this software channel
Results "Xara Xtreme" - Nothing
