Ubuntu :: Virtual Box Suddenly Running Slow / Is This Normal?

Sep 24, 2010

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?

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?

Ubuntu Servers :: PHP Suddenly Very Slow / What To Do?

Jan 28, 2011

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.

OpenSUSE :: USB HDD Suddenly Run Slow / Why Is So?

Jul 12, 2010

I run a set scripts running under cron which make tar backups to an external

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

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.

Ubuntu :: Start-up Suddenly Extremely Slow / Solve This?

Feb 10, 2010

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?

Ubuntu Networking :: Ethernet Connection Suddenly Slow - Dns Problem / Troubleshoot This?

Apr 1, 2011

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?

Fedora :: Unrar Suddenly Slow / Make It High?

Dec 11, 2009

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.

Ubuntu :: Pc Acting Slow When Reading / Writing Files From _ Onto Disk - Is That Normal?

Sep 27, 2010

Whenever I am busy reading or writing large files, or large sum of files, my computer is unresponsive. Screens are getting greyed-out and I just can sit there and wait until the reading/writing is done.
This is not caused by the CPU which is overstressed because it is not. Look at the attachments and you will see the CPU is used for about 20%. When these pictures were captured the computer was using hellanzb to unrar a long list of rar-files.
When you look at my signature you see the computer is not bad at all, just disk-access is slow. I can transfer files with a maximum speed of 30MB/s. Is that normal or is it very slow? I don't know the numbers. I have 2 SATA disks.
O.S. is Mint 9-Isadora, based on Ubuntu 10.04 and I use the 64-bits version.

Fedora Networking :: Wireless Connection Velocity Varies From Normal To Slow

May 29, 2010

I'm having problems with my wireless. It connects without any problem, but it is very slow. Actually I have the impression that the connection velocity is varies from normal to very slow, however the average connection velocity is very slow. I have been looking up the forums for more the one month with any success. I have tried to install the compac-wireless drivers and the kmod-wl with many different network setups. For sure it is not a problem with my home network, since it works fine with my other old notebook running fedora 11 or when I boot in the windows.

My system configuration is:
- sony vaio VPCCW23FX
- card: Atheros AR9285
- driver: ath9k
- operating system: fedora 12 - kernel

General :: Ubuntu 9.10 Suddenly Disk Drive Is Running Continuously - NonStop?

Apr 29, 2010

My system: Ubuntu 9.10/gnome Gateway SX2802 with Intel Q8300, 4GB ram, 750GB drive only 6 months old. My internal drive is read/writing continuously without stopping no matter what I am doing. It begins immediately after boot. It simply runs and runs nonstop. This is with NO APPLICATIONS running. This is a problem which cropped up suddenly after 5 months of running just fine. What I have tried:

1. Disconnecting Internet - no change

2. Looking at processes in System Monitor. Well, everything says "sleeping" and there isn't anything that looks obvious to me, but there are a LOT of processes. I am afraid my drive will simply burn up.

Ubuntu :: Wine System Tray Suddenly Started Appearing Its Own Little Window When Running Netmeter

Aug 13, 2010

I have been pulling my hair out trying to find out why the Wine System Tray suddenly started appearing in its own little window when running Netmeter, cluttering up the desktop. I searched the web in vain, back many tears, most people saying they couldn't understand it when it happened to them.

Then I realized that the last thing I did was to stop Cairo Dock (the novelty had worn off!) and to move the Gnome Panel to the BOTTOM of the screen in place of Cairo. I suspected this was making the Wine System tray homeless.

So I moved the Gnome panel back to the TOP, restarted Ubuntu, stopped and restarted Netmeter and the Netmeter icon appeared back in the panel where it belonged.

Would I be correct in thinking that Wine System Tray will only stay in the panel if the panel is at the top of the screen?

Ubuntu :: Slow Boot Time After Creating Virtual Disk For Virtualbox Guest

Jun 4, 2010

My laptop boot up time increased considerably (10 seconds) after allocating a virtual drive for virtualbox guest. The guest installation did not work so i removed it along with the virtual disk. Now everytime when i boot to ubuntu, after inputting my password in the login screen, it takes much longer to load the system. And during the loading time the disk activity indicator light blinks indicating the harddisk is actually busy loading the system.

I decided to search around for a possible answer and force reprofiling ureadahead does the trick Now boot time is back to what it used to be

Fedora :: FC13 Virtual Machine Manager Excrutiatingly Slow

Jul 26, 2011

I used my fc13's "Virtual Machine Manager" to install a FC14 vm image from a new iso.After a week of 8 hour days I got fc14 installed, I think that the "minimal" install option was bad. Now it takes yum 15 minutes to get warmed up. and about an hour for 1 simple package.(It was going in the background while working on other stuff, causing the cpu fan to roar with the extra load)It would be easier to install Fedora on an abacus or perhaps water clock.

Ubuntu Servers :: KVM - Deleted Virtual HD While VM Was Running

Oct 8, 2010

I've accidentally removed (rm -r) the ubuntu-kvm folder that stores the virtual partitions of my VM. The VM itself is still running. The machine is still accessible over the net (it is a webserver) but since there is no more virtual storage I guess there is no way to regain its contents. Are there any steps I can do to regain the machine? I guess if I just reinstall the machine by means of vmbuilder all newly created discs will be more or less blank.

Ubuntu :: Running MS Office In A Virtual Machine?

Jan 21, 2011

I am getting seriously tired of running MS Office in a virtual machine. It's been about 18 months since I tried running in on Wine, so I just checked out WineHQ and CodeWeavers and apparently usability hasn't improved at all.

I keep trying to use OpenOffice but whenever I open PowerPoint presentations they are always kind of messed up. This week, somebody sent me an MS Word file for printing labels for a mail merge and the label template file opened up blank. Anybody else have any brilliant work arounds or am I still stuck with my MS Office VirtualBox!! It's really hard to believe that its 2011 and Linux is still missing a world-class Office Suite...

Everything works skype ..... ( vids work but cant pause or adjust vol on player).

Ubuntu :: 9.10 Running Slow / Speed It Up?

Feb 25, 2010

I just installed Ubuntu 9.10, replacing Windows 7.

its running a little slower than I hoped it would, loading movies takes a while, and when i switch to full screen, it takes about 5 seconds to catch up.

im suspicious that my video card driver might not be configured correctly. can anyone tell me what I might need to configure to get things running smoother?

other things on the computer are also running slow, like opening Firefox, it takes a while for the window to appear.

- Athlon 64 x2 5200+
- Gigabyte GA-MA78GM-S2h motherboard
- Radeon HD 3650 512mb pci-e
- 4gb DDR2 800

and I do have ATI catalyst installed
