General :: Computer On My Network Being Extremely Sluggish
Jul 20, 2010
I have a computer on my network being extremely sluggish and I cannot find the reason why. I can ping and the response time is decent enough at 0.137ms up until something that requires network access is run(cvs, SSH, ls on mounted drives). At that point the ping jumps up to 6000ms, sometimes up to 12000ms.
I have looked through /var/log/messages and found nothing suspicious and I have not seen any problems on other networked computers when accessing the shares. Disk usage on this computer is fine(470GB free) and memory is fine as well(up to 10GB free). The computer is on CentOS 5.3.
Click on scrollbar. Drag down. Watch text crawl by in fits and starts. Don't even think about using the scroll wheel. And this, on a one page RTF document. With no special characters or images or anything.
I tried the instruction here: [URL] It did nothing. How can I make Abiword usable? It doesn't have to be lightning fast, all I want is for it to scroll at the same speed and with the same responsiveness as all my other applications.
SSH access works fine from a LAN computer, but anything over the internet is extremely slow or times out. We're talking a good 1-2 minutes just to get the login prompt!This is a new installation, I switched from Fedora to CentOS. Previously, SSH from off-network worked perfectly fine with Fedora.What could it be? All other network services on this machine are working properly and at normal speeds, it's just SSH that is not willing to cooperate.
Trying to watch movies between my systems and I'm getting upload speeds of 6.5 kb/s from my system to the one connected to the tv. I'm running Ubuntu on both machines, tried with VLC and XBMC. Both are running wirelessly but I know that this issue is new, I used to get at least a meg a second on LAN.
I've been running Suse 11.2 KDE on a 64-bit Dell Studio 1535 since last week's release, and have had no trouble using Firefox. At some point today, however, it stopped accessing webpages -- or, when managing to grab a page, it would do so without full html rendering. 95% of the time I get an error splash, while the other 5% I get some sort of truncated page that looks nothing like it should. Konquer and Opera work fine, as does KMail.
I tried deleting the profile.int file (no luck), then uninstalled/re-installed (no luck), then uninstalled and deleted every Mozilla/Firefox file I could find in order for a fresh install -- but this has not worked after several attempts. I still cannot get Internet access. How to completely wipe-out Firefox in order to allow for a totally new installation?
I switched to Chrome half a year back because Firefox had become sluggish on my Linux box (both Ubuntu and OpenSuse). 6 months later and the problem remains - anyone know what is going on and any tips to improve? I still need to use Firefox occasionally for Firebug.
My wifes networked computer connected to the network just fine when it was Win XP. Now that Ive converted it to 10.04 (completely) it can see the network, but it just wont connect to it. I had no problem converting my computer to Ubuntu and it sees the network and accesses it great. Files, folders and hard drives are all shared. So, one computer connects great, the other does not.**I dont know what to do at this point.Here is the layout:My Comp (10.04) ---------......Main Network Comp (XP)Wife Comp (10.04) -------/The main network computer is XP as it has software on it we need that does not work in Wine. The main computer will have to stay XP. I cannot get my wifes computer to connect to the main system, although mine connects just fine. I dont know what the problem is. Her computer sees the network, but when trying to connect, it times out and says unable to connect.
I have a linux machine on my university network where I usually log in via ssh from home. I have know the ip, so this is what I use to log in, but it would convenient to know if my computer have a hostname on the local network (it's easier than remembering the ip).I set up a hostname when I installed linux on my pc, but it's not the name associated with that ip on the network. Is there a way to find out if there's a name associated with that ip?
I am sitting in front of a suse server computer and i have to install php-mysql package in this server.When i am doing that through yast it is asking for the cd of suse.I have that cd but i cannot connect the cdrom to that server.The cdrom is connected to another PC which i can also access.Is there anyway to install that package using the cdrom connected to other PC.
When i first install ubuntu 10.10 the other day my entire windows shared network was visible and accessible through places/network ect.i only had an issue creating a link.Now , for some reason i can no longer see the other windows comp or any of its folders but i can see my sons laptop ( running vista) . obviously i still have access to the network and i have checked the sharing settings on the windows machine.
i want to find ip address of other computer which are connected in LAN..suppose ther are 5 compter in LAN and i want to find ip of all remaining 4 computer using my computer only in command or any other way is ther....
i have a doubt about NS3, can use the actual network card of my computer in the simulator NS3, that is, if my network card can behave as programmed into the simulator.
I'm running ubuntu 9.1 and want to access another computer on my home network. That particular computer is running XP pro. I set up the user account on the windows machine with admin rights, did the remote user yada yada yada...
I am currently trying to figure out what's the best way to backup several PCs (about 5 computers each with Windows 7) from my family.
As I want the same solution for all Computer - I set up my old computer (Windows 7) and added some hard drives and there should now be enough space to backup the data of everyone from my family via the network. (Lets call this computer "Server")
But now I am wondering whats the best way to do this? What I do not want:
I do not want to start the Server each time manually when a computer tries to backup. (I thought about using WakeOnLan.. but I do not know if this is a good idea) I do not want the Server to run permanently I do not want to make the backups manually they should backup about every week automatically.
So which Software on the Computers / or the "Server" would you recommend?
Or would you eve recommend me to use Linux on the Server? If so, which Software would you use then?
First, (for samba) how do I determine whether my computer "gets IP address information from a dhcp server on the network," and whether "the dhcp server provides info about WINS servers ("NetBIOS name servers") present on the network," and consequently whether a change to my smb.conf file, "so that DHCP-provided WINS settings will automatically be read from /etc/samba/dhcp.conf," and whether the dhcp3-client package must be installed?
its been 10 days since i have been trying to install Ubuntu 10.10. i tried every option single boot, dual boot, windows installer but nothing works single/ dual boot gives an i/o error related to cd and HDD and windows installer installs fine but my pc will hang when booting. and the biggest problem is that i dont know where the problem lies. is it my hardware or software. xp runs just fine.
I had a memory stick problem over the weekend, and after correcting the problem, I decided to up grade from Linux Mint 9 to Linux Mint 10. All video and sound functions worked properly prior to changing to Linux Mint 10. Now I can not get any sound out of the speakers, from a CD or a digital file, and a video goes at super fast speed with no sound. I am new the Linux world but learning fast. Data CD's work correctly both in reading and burning new.
I wanted to know if i can install mrtg on a client computer in network and measure the network's router traffic.i know that it can be installed on the server.
My problem is extremely slow write on hard disk and 100% cpu usage and it happens when I want to write something on the hard derive not any other external derive.
Tried a fresh ubuntu install. No change. I am not even sure if it is a software or hardware problem.
I have a firewall / proxy that has an extremely high load, but I can't figure out what's using it. No real cpu usage, the disks are sleeping except for a little log activity, it's on gigabit ethernet and not close to maxing out... Command link stuff runs fast, nothing seems slow, yet the load is sky-high. IME this kind of load is associated with a lot of disk I/O, but that's not the case here. What could be causing this, what else factors into the load?

I was using opensuse kde 11.3 for almost one year. My system is a four-core system and so far was really fast. After upgrading from 11.3 to 11.4 I have noticed that kde(?) is running slow. I can pinpoint exactly the source of the problem but just a few examples.
1. Dolphin takes so much time to load (15 seconds)
2. When I try to do something inside dolphin (like Edit->copy) can take up to 15 seconds to see the menu to appear.
3. Double clicking inside a catalog can take up to 5 seconds
I have same kind of problems with Gwenview. I can not say precisely blame kde, dolphin or gwenview.
I would like to ask your help how can I find what's the problem (any cli command, any log file to check?)
I have updates to latest opensuse 11.4 by using the documentation I found in official opensuse forumes. (Changed the repositories from 11.3 to 11.4)
Having woken her up, she is often very bleary eyed with no energy and little movement. It takes her quite a time to be fully functional. Are there any settings that reduce the time between waking up and full efficiency?
I've been using Ubuntu 10.4 for nearly a month now and am very happy with it, especially the ability to add and upgrade programmes which up till now was a nightmare with worries about dependencies etc. I do have one major gripe, and that is Firefox 3.6.3. I gather others have had the same problem. At start-up Firefox works fine, but after about 12 hours, it becomes so sluggish as to be unusable. Web pages that would take seconds to download now take minutes and the hard drive starts churning and grinding away. The whole system becomes slow and sluggish, and when I do a "top", Firefox is right at the top. Very often the only way to get out of this is to physically turn the machine off and then back on again, which I know is a bad thing.
Its not as if I am overloading Ubuntu. The last time I had to switch the PC off, all I had running were 2 terminals, a calculator and gedit. Firefox was running about 10 tabs. Even when I do a kill -9 pid on firefox and then restart it, within minutes, the system is grinding away and slowing down. The only way to remedy this is to switch the PC off. Someone else who had this problem says its as is Firefox is getting tired and needs to refresh itself completely. Is there any solution to this problem as I gather others have been experiencing it.
I recently noticed that the menus and dropdowns in Firefox 3.6 were *extremely* sluggish on my laptop running Slackware64-current. For example, if I click on "File..." or one of the folders on my quicklinks toolbar, the menus take about a second to appear. No other apps are affected and surfing is as fast as usual.I'm running Slackware64-current on a Fujitsu Lifebook V700. I typically use the Xfce window manager, but was able to repeat the problem in Blackbox.
I uninstalled the Firefox 3.6 package from -current and reinstalled the Firefox 3.5.2 package from the slacware64-13 tree and it works fine.I've been scanning the net for others having this same problem and to my utter shock I can't seem to find anyone else reporting remotely the same problem!I'm fine using Firefox 3.5.2 indefinitely, but it's driving me nuts that I can't figure out the source of this problem!
I have a problem with my Debian squeeze system. After I have run some CPU-intensive application for a while the system becomes sluggish. Ok, maybe one would expect that. But. The system remains sluggish even after that process has been killed and then top shows high cpu usage from unrelated processes and a high %sy percentage as well. I don't really know where to begin solving this problem except I've checked that this is specifically related to (at least) CPU use as opposed to heavy memory use or IO (by running an application with low mem/no io but high cpu use). I am running the latest standard kernel from squeeze, 2.6.32-5-686. Also, thing is, I remember having similar problems with other Linux distros before, where for example gzipping a large file would cause the same. I did not have similar problems on {Net,Open}BSD, so a hardware fault seems an unlikely reason to me.
1. Slow responding to clicks - Test in Mouse Preferences demonstrates it readily; the light bulb does not always light up on first click.
2. Activation of alternate window takes more than one click
3. Click on scrollbar's botton arrow remains activate and continues to move even when mouse is lifted.
4. Scrollbar randomly remains active after click on scrollbar's middle (floating) button even if mouse is move to the window area.
5. After a click on icon or link, often mouse icon changes to a hand icon and the icon moves with the mouse. Difficulty unloading this action - takes several clicks.
6. Highlighting is difficult to cancel once it starts.
This problems started with an update in 9.10 to X (which I was trying). Make the system very unusable.
I am running 10.04.1 and despite everything I have tried I cannot suss out why my machine is so slow. It runs fine in the other OS installed but in Ubuntu there is a lag to every action, eg if I drag a window it follows about 3 seconds later. Basically everything is delayed for some reason. It is becoming very annoying and I am contemplating a reinstall, could someone please prevent this. The system is running on an old Athlon 2800 and I have attached a screenshot of running processes.
