Debian :: Hogs Memory And Processor Time, Which Slows Down The Responsiveness Of The System As A Whole?
Oct 6, 2010
I'll often run iceweasel for watching videos via flash (hulu, ....., et cetera) while working, in fedora I never noticed any performance problems, watching the video while using chrome for browsing, gedit for editing, et cetera, everything was responsive. Though, now on debian running iceweasel for the same purpose hogs memory and processor time, which slows down the responsiveness of the system as a whole, making it difficult to use other programs.I'm curious how I should go about troubleshooting this issue, and what diagnostics might help me find the solution.
I find gnome-shell 3.14.2 becomes slugish after several days of use. This manifests in short delays on window functions, such as closing a window or opening a new one. Restarting gnome shell fixes it.I thought of trying to take a stack trace during the delay, but found 2 issues:
1) debian doesn't have gstack/pstack package ...? 2) attaching a debugger to gnome shell from gnome shell hangs it (duh) , which means I can't type the "bt" command
I've got a Lenny system on a quad core system with 4GB of ram. Currently Linux www 2.6.26-2-amd64 #1 SMP Thu Nov 25 02:05:44 UTC 2010 x86_64
I've had it for a couple of years, and its been fine, very fast and reliable.
Lately, its got a problem: after its been running for a day or two, access using SSH, or TLS/HTTPS gets really slow. Painfully slow. A reboot returns the system to normal fast operation.
I can't think of anything that has changed, other than I got a new SSL cert and installed it.
The system is mostly a vanity domain server, with Apache HTTPD running a half dozen very low volume services. Its running bind9, mysql, and a few other things, nothing big, nothing that would load down a quad core with lots of ram. The disk is only 14% used.
After changing servers and moving things around, I have one system which serves the /home directories, and for some reason, it is extremely slow. I've looked for duplicate IPs, signs of a HW problem, etc. and cannot figure out why the system is running with a high load, high iowaits, and low responsiveness. The servers and clients are slackware 12.2 and 13.1 respectively.
I've just added an extra 1GB of RAM memory to my laptop (HP 530). Now I have 2 GB. Everything runs great, except Compiz and 3D games. It looks like anything that's related to the graphics card now slows down. Rotating the cube lags badly, so does the Burn effect, and UrbanTerror is lagging too.
Before the upgrade, I had a Samsung 1GB SO-DIMM, 667 MHz. Then, I bought a Kingston 1GB SO-DIMM, 667 MHz too. When the laptop boots with either of the SO-DIMMs (only ONE GB at a time), everything runs smoothly, like before. But when I put both of them (regardless of the order in the sockets), my video card seems to slow down at nearly half of it's speed.
I haven't tried with Windows yet. Also, my graphics card has a dedicated memory of 256 MB, so there's no memory sharing between video and the RAM.
I just don't get it. Also, there are other people that seem to have slowdowns after upgrading the RAM, but usually the whole system is affected. For me, it's just the video. It actually boots faster with the 2 GB. Yet I found no clear solution to this.
Running Fedora 10 i686, on a 32-bit Intel Core Duo @2200 MHz, video card Intel 945GM Express, with 256 MB of dedicated memory. The swap partition is 2.8 GB in size.
I dual boot windows and ubuntu, and fount it very nice. But when i run flash game at my chrome, i can see the CPU usage increase a lot. When it reaches max, the flash game will be 'flashing' and lag. I use latest stable google chrome and flash player. Any idea how to fix this? I encounter no problem when playing at Windows.
My server is keep on hanging So I have rebooted several times in the last couple of weeks, the system is eating more memory and the usage is keep on increasing and at particular time it became saturated and my server hungs. I could not find which process is eating more memory. I have used the below commands to check if any process is eating more memory but no luck. No such process are using high memory.
I am connected to a network using any interface (eth0, eth1, or wlan0) that if my ip address was given out (dhcp) that my desktop responsiveness gets worse. Specifically the mouse has a sort of "sticky" feeling. I mean by that that I'm moving the physical mouse and the cursor is getting stuck here or there on the screen. It is extremely annoying. Here is my config file:
beethoven:~$ cat /etc/dhcp3/dhclient.conf # Configuration file for /sbin/dhclient, which is included in Debian's #dhcp3-client package. # # This is a sample configuration file for dhclient. See dhclient.conf's
Installed Karmic or upgraded to it, and the Time Date in the upper right loses time now after upgrade to Karmic. Worked fine before upgrade so it is not hardware.
Ever since I turned on my notebook yesterday (Compaq Evo N610c) my processor has been working 100% all the time. I checked processes via System Monitor, and no process is doing such thing.
What can I Do?
Here's a copy/paste from top command
Code: [juan@x22 ~]$ top top - 11:02:39 up 37 min, 2 users, load average: 2.77, 2.21, 1.48 Tasks: 142 total, 3 running, 139 sleeping, 0 stopped, 0 zombie
I'm working on this Intel Celeron HP33w Pavillion with 512mb ram and a 180 gb hard drive. Installed xp on it, partitioned half the drive and left the other half blank. xp installed no prob, then installed ubuntu on the second partition letting ubuntu create the partition and swap space (which was 3 gigs) and it installed fine (aside from being incredibly slow to go through the actual install process). Once finally booted into ubuntu with no other programs running aside from the standard ones that start with ubuntu, i added the system monitor to the panel and expanded all the other monitors. Memory was normal, cup average was 100% and cpu usage was 100%. Figured something went wrong with the install so I reinstalled and got the same result. Window xp runs just as fast as it should with 512mb of ram so I'm sort of at a loss as to why ubuntu is eating up all my memory with no programs running.
I ran Karmic until last week, and noticed that it seemed to be getting slower. I was hoping a clean install of Lucid would fix that. it's worse. If I leave my machine running for a few hours, something begins dragging down the performance to a crawl.
System Monitor sometimes won't come up - launches an empty grey window. Other times, System Monitor reports that gnome-system-monitor is consuming 86-96% CPU. This is a dual-core Dell e6500 laptop with 4 Gigs of RAM, it should fly. Any ideas on troubleshooting this?
I use a Debian Squeeze system running off a flash drive, i.e. based on a custom Live image running in persistent mode. It runs great and I am grateful for the existence of Debian . However, I have a question. A lot of the machines I use this pen drive on are quite old, often with 512 MB RAM and old processors. I specifically built my system using XFCE and lightweight apps off an initial live image using the standard-x11 package list (basically just Xorg with drivers and the base system). At first things ran very well, blazing fast even on the oldest systems and could comfortably run Firefox along with LibreOffice side by side (I need LO as all of my colleagues use Word docs, often with track changes, which Abiword can't handle properly). However, over time, I've found that memory usage has risen, tot he point where Firefox is now automatically killed on the older systems every time I start LibreOffice.how does one figure out why memory usage is going up? I've checked for inessential services and turned them off with "insserv -r". I've used only lightweight apps, as mentioned before. Are there other general tips on reducing memory usage?
I have a newly installed Dell Optiplex 755 with Ubuntu 10.04 (64-bit) and I am having serious issues with network copying. Whenever I start rsync och scp with larger amounts of data my system becomes practically unresponsive (all types of apps grey out) until those processes are completed. Cpu stays at below 10% and I have lots of free memory and such .
My system slows much down so that i cannot use it at all when am watching any online videos or movies am using firefox 3.6.13 .
My spec is: intel celeron 2.53 Ghz 512 Mb ram ubuntu 10.04 on 40 GB seagate ide harddisk Windows Xp on 80 GB western digital ide harddisk in dual boot.
And also my browser cannot open login page of yahoo site and some time it waits saying waiting for s7.addthis.com, or waiting for ad.yieldmanager.com like some thing when i am trying to open some sites
I noticed that sometimes my Linux server will randomly start to lag really badly, to the point where even a http request takes forever. It is an Intel Core2Quad with 8GB of ram running FC9. This is my "Everything" server so it does file, email, DNS, web (for local stuff only), VMs and so on. There are about 5-6 VMs running on it at any given time. I manage it through a VNC session and have some SSH consoles within that session. This way if I reboot my PC I don't lose all my SSH consoles. If I need to SSH to any server I do it from there. I treat it kinda like a terminal server to some extent.
When this slowdown happens, top is not really useful because I also do F@H so that will always be to the top, but it's low priority. The VMs are also always near the top. This does not change whether it's slow or not, so when it's slow, I have nothing to go by on how to troubleshoot. The load does seem to skyrocket though. Right now it's doing the slowdown thing and it's at 8.09. Normally it's at around 3 which imo is good as it it's under 4. I have 4 cores so anything more than 4 means it's queuing. At least that's how I understand it. This is the output of top:
I have some questions.First, how can i obtain a process execution time ( after it terminated)??? Second, in a multi-core system like SMP how can i run different processes on different cores explicitly? i.e. how can i assign a process to a specific core?

I use Debian Testing with the default Clearlooks theme - (nvidia graphics, 32-bit kernel 2.6.38-2-bigmem) For some time i noticed Nautilus opening folders slowly. I did a gtkperf test and i was surprised that i got 12 or so seconds. Before i had ~3 seconds. Gtkperf test output with the libcairo2 version 1.10.2-6 (notice the high GtkComboBox and GtkToggleButton values):
When I try to install Debian 8 on my laptop I get this rather odd error. The install fails every time. I've managed to get as far as choosing which Desktop Environment I want and the shortly after it shuts off. It shows 4 messages
The machine I'm trying to install on is a Gateway NV53, 4gb of RAM, AMD Athlon II x64.
At first I thought it might be my disc so I burnt another DVD using the 4.3GB DVD image I had downloaded. I checked the disc and it verified with the image and so I tried again with the same results as above. Any clue what might be causing this? I'm sure it isn't my hardware, Arch has been running fine for almost 6 months and never seemed to care.
Why there is too much error in every version of gnome-shell and after everything slows down after a few hours of working in gnome-shell on debian(only on debian, i'm using gnome-shell in fedora and excellent experience i had in it) some of syslog output :
i have a debian 5 vps system.. it reports the time as beeing one hour behind, i have tried to change this by setting the time to GMT+1 and setting the time to my local region (Europe-Brittian) using the tzselect command but none get the time to the correct time, one hour ahead of the current time.
I seem to have run into the bug where my system was suspended when the DST change occurred (Not off so it didn't do it on reboot, not on so it couldn't do it then). I can't seem to find any way to do it manually. Is there any?
I changed to the kde desktop environment. I logged in as a normal user, and left the computer running for a few hours. when I came back the screen was turned off and the system does not respond to mouse movement, pressing the keyboard, or any combination thereof. I tried
Code: Select allCtr+Alt+F1, CapsLock
First time i touched keyboard the led of numlock turned off, and never back. Blanking the screen itself does not cause a system crash, this occurs after several hours of inactivity.
.xsession-errors Code: Select all/etc/gdm3/Xsession: Beginning session setup... localuser:bartek being added to access control list openConnection: connect: Nie ma takiego pliku ani katalogu cannot connect to brltty at :0 Failed to connect to the VirtualBox kernel service
A few months back I performed a routine aptitude upgrade on a Squeeze installation on a DELL Vostro desktop. My eth0 upload speed is now very bad although download speed is good. I suspect that it could be related to my other problem [URL] which was caused by the OS enabling noveau driver instead of the installed NVIDIA proprietary drivers.
I installed Ubuntu 10.04 on an 8GB flash drive, and through much effort, was able to boot it on my white MacBook (2Ghz Core 2 Duo, 2GB RAM). I find that responsiveness is really poor, for example, the display frequently freezes when I switch windows, or load a web page. Is this expected for Ubuntu that's running from a flash drive? Are there ways to improve this?
i have installed ubuntu in my laptop.since i have AMD processor fedora doesnt support AMD processor..the recent version fedora 12 supprots AMD processor.i am doing my final project in ns2 hence it should support tht too!!! Which is the best choice to override ubuntu grub fedora 12 or redhat linux.
After installing the 32 bit desktop version 10.04 on vmware 6 and then rebooting ( a number of times) I get the message "the guest operating system has disabled the processor". This doesnt seem to happen when I install the 64bit version though. I have 9.1 running in 32bit versions in vmware and several other operating systems.I am not sure if any of those things would cause this issue but I have read in posts about people having issues with RAID and speed stepping. Hopefully that info can help spmepne point me in the right direction. Thank you.
The computer went into low graphics mode all by itself and then later threw a error that said incompatible processor system halted!the computer was getting really slow and made alot of noise.later the computer did something stranger..it restarted but normally when my computer normally restarts it bypasses the password page setup in bios of the computer. This time I still had to enter a password before it could reboot.Another thing...when it the ethernet cable was connected to the computer (internet connection was on) it was slow when it was unplugged it was not.I have read that unless you're running a server or something it is highly unlikeley you'll be hacked.
