Ubuntu :: Stress Testing Installations For Performance And Stability
Feb 13, 2011
I'm going to be installing Vinux which is Linux for the Visually Impaired, based on Ubuntu, onto most any computers I can get my hands on to give to the VI community around my area. I'd like to know what would be a good method to stress test each computer to ensure that each one will operate at an adequate speed without freeze-ups. Sorry, I can't be specific about the computers. I'll be taking whatever gets donated from the public and from businesses, desktops and laptops, whatever comes my way. I don't want to send out any headaches to anyone by giving them a dog-tired slow or a freezing computer that won't even operate.

I have been assigned a project in which I have to test File System stress testing using "Fsstress" tool. I have to do this for a local file server. I don't have any idea as how to and what to install FSSTRESS on the Linux machine. I searched an rpm package and installed it on File server however, I don't have any idea about the commands and working of the FSSTRESS. My task would be successful if I can just run few stress testing test cases using FSSTRESS and come up with test results.

Is there any program for GNU to calculate CPU's performace in marks (should support multi-core CPUs)? So it will be possible to compare performance of different CPUs.

I would like to test network performance, to get statistic information. Is there any tools where I could specify partikular message size send as a constant for many times and in an output I could get time for each transaction? There is a tool called ApacheBench, it is for webserver testing, but I would like to find something similar for network testing. I have also tried Netpipe, Netperf, Iperf, but they do not show information in an output, which I would like to see.

I am trying to set up linphone for testing voip performance. Essentially I am a beginner with linux. I picked Fedora based on the recommendation of a friend. I am running Fedora 12 and I need to get linphone up and running with a working registrar. I have no idea what to do so I turned to hours of research which yielded little results but I did thing to try using partysip. I would like to know if this is a wise choice and if it is what do I do to set it up?

Now doing some research about performance of Linux switch. I'll start with basic structure of my system: PC1 is connected to PC2 - both have 1 NIC so not much to add.PC2 eth0 is divided in VLAN`s as far as maximum of 4094. Every VLAN has it's own switch (bridge). On PC1 when I run a test I just make VLAN/configure IP address and stream data to IP that's configured for that bridge on PC2.But now I want to add one more interface to each bridge, so I could stream from PC1 through bridge to Virtual interface (just an endpoint out of bridge). I could possibly add one more computer, physical interface to PC1 and make it work, but is there any way to make this work with virtual interfaces, like tun or something? Making just a simple tun interface and adding it to bridge, as you understand, doesn't do the trick, I need some kind of other endpoint that /virtually/ connects to tun interface. Maybe someone has made some kind of script or something? Using Iperf for my tests.

I have an issue with my Dlink DWA 547 802.11n PCI adapter, I'm under LUCID fully updated.I have no trouble connecting to any wireless but after a few minutes I'm loosing the connectivity strenght (getting ping reply from my router that vary from 2ms to 200ms). But as soon as I'm rescanning the network using the command (sudo iwlist wlan0 scan) everything is fine (constant 1-2ms ping). I'm using wicd as network manager. I have tried to schedule a job in crontab to launch every 10min a network scan command, but didn't succeed to have it working, morehover I don't think that's the good way.

I just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

Just put an old desktop to work by installing Puppy on it. I have another HDD that I think didn't work very good, so I'm gonna plug it in and test, but I don't know what to use to stress it.

I've heard that some people have been running maverick with relative stability, however I remember experimenting with lucid in about the same stage in development and it was a disaster. Is there anybody here running maverick for day-to-day use?

I'm looking for system stability test software to stress test all of my hardware. I used to use Everest on windows, and I found a closed source program called burnintest that should do what I like, but it uses KDE 3, which I never use. Is there a ubuntu friendly (open source a plus) stability software in existence?If nothing exists, I'll have to make one.Waspinator[URL]

After turning off the overclocking (When I actually turned it off, I realized it didn't really make a noticeable difference) of my CPU and lowering the fans of my PC, I would like to stress test the GPU/CPU, and obviously also check the temps while doing so. The fans on my PC were previously so loud you couldn't even have a conversation on the phone while in the same room as the computer, and I just now realized how much I can actually lower them... But I don't want to lower them too much, obviously.
So, anyway, because of these reasons I would like to stress test my CPU/GPU while monitoring the temperatures. I'd need software for doing so, Linux or Windows doesn't really matter, I have both. Also, I need to know what minimum/maximum temperatures that are okay.

1. Sometimes when I try to shutdown my computer the display becomes filled with pixels of different colors as shown in the image (The problem is very random so I was not able to take a photo, I tried to recreate the effect using GIMP). Then the display turns off (Analog power saving mode) But my system never turns off.
2. While working on my computer the display sometimes goes kaput and blinks as in the second image. It stops responding completely I am not even able to go to terminal (Ctrl + Alt + F1). Leaving me with no option but to use the reset button. Causing me to loose all the work in progress.
3. Firefox responds very slowly upon closing it takes 5-6 seconds for the window to close.
PS:- KMS is also disabled in my system. Enabling it didn't improve stability. and here is the output of my videocard (lshw)

Ubuntu 10.04 x86. Yesterday I installed 10.10 and had lots of trouble with wireless stability. I formatted the partition and installed 10.04. My wireless router does not show up in the available routers list. Neither in the list that immediately shows or under the More networks submenu. Lots of other routers from adjacent homes show up, but not mine in the other room.
Why? It shows up on all of my other computers. My MacBook, Windows 7 (different partition on same box), my older Ubuntu netbook,and it showed up on a previous install of 10.10 (though it could not maintain the connection longer than 5 minutes). It will not show up on Ubuntu 10.04. I've tried manually entering the information to connect, but it doesn't see it. I don't know what to do.

I had made a database in OOO Base, but I guess because of the size, it's not uncommon for it to crash. Now that testing and Sid are now using LibreOffice, is the database any more stable? Or...is there an alternative database package to be used only on a local machine without a server?

I have atheros wifi chip and I got wifi through madwifi. I was using f9 and my wifi connection in very stable. Then I tried F10. It has already firmware for atheros in it kernel. It get connect through wireless network (wifi) but soon it disconnect. I updated NetworkManager but no fruitful result came. Finally again I switched to f9 and I got very stable connection. But I am missing the features of f10. I hope that the connection will be stable in f11. I tried to install f11 but it says /dev/root not found again it shows that something clock time at the time of booting and it stop booting. So finally I choose to use f9.

I've just tested my new (actually old as hardware) nodes in computing cluster. Use for this http://systester.sourceforge.net/. But in params for tester above 32M system refuses to allocate memory in spite of there are about 250M free.It's because it too defragmented so i cannot run such tester. In future actually will be tasks with big linear memory queries, so is it possible to defrag RAM after every system loading?For this moment can you also point out for me other testers weith big memory queries but without linear manner?

So my netbook has overall very generic intel hardware Atom processor and Intel Graphic card the only component that requires a proprietary driver is the broadcom wireless card (unfortunately brcm40821 does not work for me) I am running opensuse 11.4 and I am willing to update the broadcom-wl driver each time there is a new kernel update in tumbleweed I am just wondering as of now, how stable is Tumbleweed (anyone has had any problem or success with tumbleweed, welcome to share in this post)
PS: I read (in the announcement/news section) with the new kernel (2.6.38-18), samba is finally working fine alongside apparmor.

I'm developing an embedded Linux (it is almost over now). What I'm struggling with is the system goes unstable by cutting power source frequently and it does not boot anymore. It even does not perform fsck. The system just has a XFCE with a fixed Qt App autoloaded to display some charts. My question is that how commercial embedded Linux distros (like Wifi AP's management Linux, ...) avoid this problem?

Is there a way to have grub2 managing two installations from ubuntu on the same pc ?I have two partitions, one with karmic, another with lucid. Grub is detecting automatically the two or more kernels, but assigning them to the same root partition.Is there a way to make update-grub, detecting lucid kernel, and assigning it automatically to lucid partition, and the same for karmic ?It seems, that os-prober, detects the lucid installation from karmic, and print the correct corresponding partition on the screen, but in the config file, the root partition is the wrong one, and os-prober doesn't detect karmic...

Is there a way to pause installations/updates? If there is not, would it be possible to implement that?It seems these days that installations through synaptic seem to take ages to download files. While downloading the files, ubuntu will not let you run any other package manager. So if I am updating my system or installing several programs through synaptic, I am unable to install anything else. For example a deb file ive downloaded, or i would like to install a single program while all these other files download.
I can understand not being able to install multiple things at once, but why is it not possible to install things while it downloads the files? Sometimes it days several hours/days to download the files.
