I've just noticed that unrar is suddenly taking minutes to extract instead of seconds.
I can remember if its recently been updated, but I've uninstalled and reinstalled it and the version is: unrar.x86_64 0:3.7.8-3.fc10
I've found a few Ubuntu posts about it on Google, but in true Ubuntu fashion nobody has any answers!
What's odd is that when I unrar a file from (Nautilus or "unrar x *.rar") it takes say 4mins, then if I do it again it takes 15secs, like as if its caching somewhere.
All of a sudden, the startup (time from GRUB to Login Screen) has been quite slow. I recently installed a LAMP server. I've tried disabling httpd and mysql but it didn't seem to have any effect. I've attached my dmesg output below.
I am using Redhat linux 9.0 and using squid proxy server.My problem is tht i my squid server is responsing very slowing. whenevr i try to open sites the site starts to open after 3 or 4 seconds and often squid does not open the complete site. its stop the site in middle. My squid Configurtion is below. Is there any need to tune the system parameters Like from 'SYSCTL.conf' for better diskd performence or another problem. at this time i am using default system parameters. Please help me in detail what is the reason of squid slow performence if there ia a need of any system tuning please tell me in detail. I am very thankfull to you.I am really worried about slow performence of the squid. I also try to offline_mode on but the same problem. code...
I have a .rar file called Japanese, and every time I enter the command "unrar e Japanese.rar", I get the response "Cannot open Japanese.rar No such file or directory No files to extract".
I've done everything on this site, but I can't get it to extract. What do I have to do to make this work? Do I need to set the directory or something? I've seen other people mention that as a solution for other problems, but have no idea how to do it.
I have CentOS 5.5 x86_64 with Apache, php and mysql. I have just installed OTRS (helpdesk - trouble ticket system) on that server and no users. This system works with perl, apache and mysql. I notice that is slow to respond and at times unresponsive the apache welcome page. code...
So I just reinstalled OpenSUSE 11.2 and I went from having 20-30 mbps speed to and from my 1 tb usb ntfs external hard drive to having about 1 mbps transfer speeds now. Is there any suggestions for how I can fix this? I know it can go faster, I just need to figure out how. and would setting acpi=off at boot affect this?

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'm having issues playing HD videos ( some with 720p level, much more apparent with 1080p level one) The video appears to slow then becomes choppy, becoming de synced from the audio that carries on as normal. This occurs with both VLC player and XBMC, though the latter is better. My specs: Fedora 12 3.2 Ghz P4 processor 1Gig ram Radeon 9800 xt gfx card (I couldn't get the 9.3 ati driver to work)
I try to open an application, and it's painfully slow, and i think "this is weird i've had it open just 10 seconds ago and it should be in the cache". the disk is constantly working, so maybe i ran out of ram and it's swapping, so i check: according to 'free -m', about 200m of 2g ram is used (without buffers/cache), but still also 200m of swap is used, although swappiness is set to 1 (low tendency to swap). so this is not normal.also, kswapd0 is eating pretty much cpu (but not 100%). switching to tty1, logging in, and starting iotop takes about a minute. according to iotop, about 8 random processes (could be a browser, could be some daemon) have 99% IO activity (i'm not sure what that means, how can 8 processes take 99% each?).after the first 3 times, i disabled swap by adding swapoff -a to rc.local, but it's still the same, and kswapd is still among the cpu-eaters.
I was browsing my folder with lots of images, after finished i close nautilus and i notice that my computer became slow, so i'll check it with system monitor and had found that nautilus are using almost 100mb of ram (opening 4 tabs). I'm not sure if this was normal or not because i try to reopen the same folder with pcmanfm and it only consumes less than 20mb of ram (opening 4 tabs). here's the screenshot from system monitor .
Several days ago, I replace my PC's motherboard and now sound is too low - I can't hear practically anything, I used alsamixer to configure output volume level to normal, but this won't survive reboot. I tried to use 'alsactl' and saveed rules, and edited rc.local to restore - but it didn't help. Can anyone tell me how to fix it?
I run a set scripts running under cron which make tar backups to an external USB HDD.
Wednesday (7 July) night backup 22GiB took about 15min Thursday (8 July) night backup 22GiB took 5hours 44min :-o
Nothing changed between these runs, the machine wasn't rebooted, the USB device wasn't unmounted and remounted.
This has been a basic speed change - everything prior to 7 July runs at a similar speed and everything since then is dead slow.
I've googled around and come up with things like ... * Make sure the device is mounted async - I believe it is (options: rw,defaults) but it wasn't remounted in between. * Make sure that ehc1_hcd is loaded before uhc1_hcd - the entry in /etc/modprobe.conf looks like it is and anyway there wasn't a reboot between.
I dread to think how long a full backup is going to take so I could definitely do with getting back to the sort of speeds I used to get.
Shut down speed all of a sudden became slow.. I'm running 10.04 on a dual core 3.2gig cpu with 4 gig ram. Boot up is in seconds and shut down was almost instant. Now shut down takes about 15 seconds. Is there a way to see what is causing ubuntu to hang when shutting down?
All of my PHP web pages are now loading incredibly slow. I created a simple "Hello World!" script and timed retrieving it from a terminal using wget and it took 3min 9seconds. A wget of the home page of a PHP-based site also took 3min 9seconds. I have a PHP script that I run from the command line that I use to look for malicious FTP attempts and it took - you guessed it - 3min 9seconds. I am running Ubuntu 8.04 LTS and have applied all of the latest updates for that version.
One thing I did notice was a proliferation of apache2 processes. With every request for a page I seem to get 7 or so new apache2 processes.
I have a dell dimension 4600. I just recently installed kubuntu 11.04. It was working fine for about an hour or so, and then it suddenly became slow and unresponsive.
I've been having a problem in Ubuntu 9.10 recently where starting about 2 minutes after startup my computer slows down and becomes unresponsive. I believe the problem is associated with a high IOWait because I have the system monitor applet on my Gnome Panel and it displays 100% IOWait every time my system starts to slow down.
I have tried booting into other kernel version and the problem persists. I don't really know what IOWait is or how to diagnose this problem further. I've looked around online and it seems like you have to find a specific process that is causing the IOWait, but I don't understand how to go about doing that.
I've been using Ubuntu consistently for about three days now. I really, really love the interface and how everything works and all that, but I've been having a couple of weird problems with speed.
Graphics things seem to work really well. When I go into the overview of all my workspaces, it's instant and looks great. The problem is when I open and use some applications.
For example, when I open up the software center, it takes longer than it did the first time to start up. Also, when I drag windows off from being maximized, it takes literally about five seconds for it to show up as being dragged around by my mouse.
When I look at the system monitor, about 20% of my CPU cores are constantly being used. That's 20% each. I have a 3-core CPU, could that be the problem?
Another example: when I went to ..... just now, it would take a second for any volume changes in the video to register.
And I also have smooth scrolling in firefox, but it's very unresponsive now. It's slow as all hell. Even notifications are showing up more slowly.
So, what's the deal? What could I have done wrong?
CPU: AMD Phenom II X3 2.8Ghz GPU: ATI Radeon HD 4860 1gb RAM: 4gb
One more thing: I have really bad screen tearing when I try to move windows around, as if there isn't any vsync on. Where can I turn it on or fix this?
I'm still pretty new to Ubuntu and Linux, but I'm an advanced computer user. Since I feel linux is killing my CPU I think I'm going to boot back into Windows 7 for now, but if I can fix this problem I think I want to keep Ubuntu as my main OS after this, having Windows for games, unless I can get Wine to work right with them.
I am a newbie regarding the Slackware, though i have some millage on Ubuntu. Anyway, i have Slackware 13.1 and slapt-get is really, really slow when downloading packages, even when i do slapt-get -update the slowness is just killing me
The second question is somewhat different. How can i view dependencies on which a particular application is depended?
After having downloaded unrar, I find I can't actually use it to extract rar files. Whenever I use the command unrar e filename.rar, (obviously using the correct filename), I just get told there's no such file or directory.
I don't think any changes have been made to my laptop, but it suddenly loads Ubuntu extremely slowly. The time it takes to get from the Toshiba boot screen to the Ubuntu Log-in screen takes easily 20x as long.
Has anyone else been experiencing this kind of lag or have any ideas where to begin?
I have a VM setup in VirtualBox of Win XP. This VM has been setup for well over 4 years.
All of a sudden today, the VM started running very slow. I checked the task manager in Windows, nothing eating up PCU or memory there. I then ran htop. Attached is what I saw. There are many repeat processes with different PIDs. Is this normal?

A couple of days ago my internet connections suddenly became very slow/intermittant.
I thought the problem was at my DSL provider but after more checking the problem seems to be in Ubuntu/Linux somewhere.
Reason: I can dual boot with windows 7 and have no ptoblem at all. Also I tried a Ubuntu laptop on the same router ethernet port and it also works fine. So its not my hardware or my provider, and its not a general Ubuntu problem either.
There are no error messages in any of the /var/log files and ifconfig looks normal.
It seems to be a DNS problem as it's the initial connection to a host which often times out. If I get a connection, I can e.g. stream an radio station fine.
If I try to e.g. traceroute any host it times out (no reply).
Ubuntu 10.10 is totally up to date as of today.
I'm stuck! How can I troubleshoot this to find the cause?
I have problems with my network speed when i ping my proxy server I end up getting a high packet loss generally more than 30%.I have tried to use various network monitoring softwares like etherape, wireshark, tcpdump but I am not able to get to the bottom of the problem.basically I am trying to find out where the lost packets are going.
I am having a very weird problem, of which I have never heard before. The problem, shortly (I will give details in the following), is that the copy speed between the partition in which I am running my Fedora and another partition where I store backup data is 50K/s, which is extremely slow (it has been usually around 10M/s, almost 200 times faster).
My laptop is a HP Pavillion Dv7 2080 ep, in which I have two disks of 250G. One of the disks is partitioned between two operational systems, Fedora 14 64 and Windows 7 64, and the other disk contains the above referred partition where I store my backups (lets call it backup disk). The problem happens ONLY when I try to copy anything from my home in Fedora to the backup disk. I first thought it could be a problem in the backup disk. Then I login into the windows and made a copy of some AVI files (3G approx) to the backup disk, which went normally, within a few seconds, thus eliminating this possibility. I try therefore to make the inverse process, a copy from the backup disk into my home folder in Fedora. It went normally, copying 4 G also within few seconds, actually with an excellent speed of 50M/s. After searching in google, I saw some people also complaining of slow copy speed (although they had 7M/s, more than 100 times faster than what I have now), and one cause could be that the source file system (in my case the Fedora home folder) would be near its full capacity. I therefore eliminate everything that I could, around 15G, and now I have like 20G of free disk space, which I think is more than enough for everything. However, the problem persists. Some people also said that it could be the type of files and/or amount of data. I therefore tried several kinds of files (from raw data files to AVI and RMVB regular video files), and several amounts of data (from single files with a few Megas to folders with 20G) and in all cases I had the same unacceptably low copy speed of 50K/s.
It seems to be a problem in the software, caused by the updates, since until 10 days ago it was everything ok. However, I usually make the updates whenever they appear but make my backups much less frequently. Therefore I don't know for sure what has changed in Fedora through the updates since the last backup I made, when everything was working fine.
Motherboard: Asus P5KPL-CM Audio Chipset: VIA VT1708B
No linux sound drivers on Asus' site. No ubuntu 9.10 drivers on VIA site. Low sound with default drivers. I've edited /etc/modprobe.d/alsa-base.conf with options snd-hda-intel model=3stack, but no luck. I actually had to do a sudo sh then edit it that way with vi because it was read only. Didn't do anything.
I just built my first computer from the ground up and installed linux x86_64, FC10, and among other problems, i cannot get the volume of my speakers to play much above a low volume. i have the pulseaudio volume control set to 100% for the output and input levels. i adjust all my video and audio players volumes to the max also, but the volume from the speakers is still very low. the speakers worked fine with my old hp computer. is there anything i can do, adjust to fix this?
