Ubuntu :: Disk Very Slow After Going From 9.04 To 10.04 / Make It Up?
Oct 1, 2010
My disk is very slow after I installed ubuntu 10.04 over my old 9.04. Doing some tinkering helped a little code...
But it is still far too slow. On the other version, I had a custom partition setup, with the home partition with 100GB, and ext3 (and other partitions for swap, boot, root folder and space for a windows partition I never cared to install ).
This time I am using a standard Lynx setup (2 partitions, the swap and the main one with almost 250Gb, using ext4).
Some applications I develop, that use disk for some unit tests, are now very slow to work with. Is there a way to making it faster? Going back to 9.04? Waiting for 10,10? Gparting and making partitions smaller on ext3? I don't know if any of these will work.

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.

Whenever I transfer a movie into my 16GB USB flash disk, my whole system becomes windows-like and unusable!
When i drag the file(s) into the USB disk folder, it starts out fine and pretty darn fast (25mb/sec) then slowly decreases until it's unbearably slow (3m/sec) and as a side effect my whole system starts deteriorating. I basically have to wait for the file to finish transferring before i can use my desktop again!
This has been happening with every version since Karmic (all 64bit)- I put up with it because I don't use the USB stick that much.. but lately it's been my go to source for transfering large files to/from work.

There is a disk 500 gb, it is broken on /boot and on /root and on /dev/sda1 and /dev/sda2. Whether prompt it is possible to redistribute a disk without loss of data namely it is necessary to make/boot and two equivalent on disk volume.

This is a curiosity of mine, and I expect a technical answer, if someone knows it. Why the systems become so irresponsive when doing hard-disk input and output? This happens even if writing is done to a secondary disk where neither the system or the swap are stored.

I've stopped the download several times already due to it being so slow. I resumed the downloading at file 1991 (out of 2046 files....) but it's not budging from there. Are there really so many downloads going on today it is making it hard to download?

I worry about mounting properly an external USB hard disk.
It is a sata 1To NTFS formatted
It works perfectly with a XP SP3.
With xuxbuntu 10.10 , with ntfs-3g installed , it is VERY long to transfer data:it took almost 3 days for 360Go.
When I connect to the station , it automatically mount by itself on /media/disk without any option;I suspect bad options are used and no use of NTFS-3G.
How to oblige it to mount with good options?

I am running Ubuntu 9.10 x64 on a relatively old laptop and I find Grub is taking about 20 seconds to initially load before booting the system. The laptop only has a single 120GB hard drive, and I chose the "use entire disk" option when installing, so I do not have any fancy partitioning scheme.When the system boots I get the "LOADING GRUB" text displayed and then shortly after it just shows the flashing cursor with no text, and stays there for about 20 seconds. After that it finally starts loading the system.All the searching I have done only turned up solutions relevant to people with multiple hard drives. This was not an issue on Grub 1.

I'm running Ubuntu 10.04 as a full install from a USB flash drive. In other words, I've installed to the flash stick just as though it were a normal hard drive. This is not a Live USB/Persistent install.
The drive is an off-the shelf 8GB Gigaware stick, and its read/write performance is pretty slow. Any time I do anything that requires disk access, it's very sluggish and tends to hang.
I'm looking for advice on things I could do to minimize the amount of disk-access made in the course of using the system, so that it will feel snappier and more responsive.
Some things I've done already:Installed 'preload', which is a daemon that monitors what programs you use frequently, and pre-loads them into RAM to reduce startup time. Mounted /tmp as a tmpfs (RAM disk) and moved my Firefox and Chrome browser caches into RAM. Set noatime for my root and home partitions.
Should I be trying to disable the filesystem journal as well? I'm less concerned with potentially burning out the flash drive with too many writes than I am with just making the system more responsive and nicer to use.
One other thing I was reading about is the so-called "Laptop Mode" that appears to be kernel settings to allow you to spin down a laptop hard drive: [url]
Obviously a flash drive doesn't spin, but it seems like some of those same techniques could be helpful here. Is there anyone who has experience running Linux in a situation with a very slow hard drive?
The computers I'm using this flash drive with all have between 2 and 8 GB of RAM, so moving more stuff into RAM is unlikely to be an issue.

How can i increase the IO rate. I have another HP Proliant server and there i can see 98 MB/s speed of IO which is quite good.

I posted this yesterday, but my post completely disappeared (I looked high and low -- nothing.)
I am using Ubuntu Server 10.04, all the latests updates.
For an FTP Server, I use ProFTP.
One specific directory, and it's subdirectories on my server will not download at a reasonable rate. They move at about 17-50KBPS.
All other folders work fine, at around 1.5-2.5MBPS.
What is going on? I have no idea how to troubleshoot this. The files being transfered are in a directory under home. They should have no permissions issues (I reapplied the permissions I want already), I tried restarting ProFTP, the files vary in sizes (from a few kilobytes to about 120 megabytes).
I use Webmin for most web management.
I am not having overload issues with my network card or CPU utilization while downloading these files. They are being accessed from the local network.
This issue is taxing because the files in question are backup files.

I recently install Ubuntu 10.04 on my computer and enabled the top effects option when choosing desktop background, screensavers etc. It worked fine for a couple of days then started to take about 3-5 seconds up maximize any program it ran - it minizes them instantly but takes ages the opposite way around.
My laptop has a core duo processor, 3gb of RAM, a ATI 3400 512mb graphics card, when I ran Vista on it, it could easily handle Vista built in effects and run Crysis well on low settings - I very much doubt the problem is that my computer isnt powerful enough. Is there anyway I can get Ubuntu's special effects to work properly again? Atm normal effects wont work either - I am having to use the No Effects option.

I have read many threads but cannot find a solution on this code...
Now no matter how i transfer if its from HDD to HDD or to SSD i never get more then 18-20MB/sec, i just tried booting to my live CD and was able to transfer with 24-25MB/sec
This is really slow, since the worst (2.0TB) can do a minimum of 30 READ
Anybody got any ideas, this seems to be something that has plagued ubuntu for years, and no i don't want to try other distros, i tried almost all of them a year ago and finally went with ubuntu

I have Ubuntu 9.10 64bit on an AMD dual core proc with 4Gbt RAM
I have installed XBMC from instructions here...
http://wiki.xbmc.org/?title=HOW-TO_i...n_step-by-step
I got as far as...
""XBMC is now installed and ready for use."", re-booted and loaded program.
It loads OK but I cannot access/select the menus because the mouse pointer bears no relation to the mouse and the keyboard is no help either. Both are incredibly Slow!

10.04 boasts a very quick boot time, but after upgrading, I've been having a much slower boot than in 9.10. It hangs at the screen when it says
Boot from (hd1, 0) ext3
Starting up...
It stays at this screen for a good 15 seconds before showing me the login screen. I've attached the results from a boot info script.

I have an Ubuntu Server 10.10 install on a VIA C7 chip. It seems to pause for about 5 min on a USB component.
It is a fresh install, here is a snip from my messages log code...
My KB is USB, so I would rather not disable it if at all possible. The next time I can take it down, I will test disabling it though...

I have installed Kubuntu Lucid on my Samsung NB30 netbook. Got everything working, but the disk access seems extremely slow and noisy. Whenever larger files are being processed (software installation), the disk makes a kind of rattling sound - looks like the head is moving back and forth between two or more locations. The disk seems o.k. so far - no io errors under Linux and Windows XP boots without problems.

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.

My first post. I've been using Ubuntu Server edition (Hardy) happily for some time now.
I use sudo regularly during configuration of new services. It always works/authorises within seconds, however, it recently became very slow, to the point of being nearly unusable.
In /var/log/auth.log I noticed a regular working pattern like this code...

Ditching Windows for the last time but this seems to be a issue wireless seems fine for a bit but then the connection slows to around 20kbps or worse. Any ideas what it could be? Using 10.04.1 it says it has a 48mb connection and i have 4 bars.

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

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'm a truly ordinary shell scripter (and unfortunately I know nothing about any higher-level language), but I have an important script to run to count the number of files in our client directories.
Problem is that while we've not got a lot of clients (circa 100), they might have a LOT (> 1000s) of files.
And my script is REALLY slow code...
PS How slow? Well I started a cron job at 0005 yesterday, and as of 0930 today its only a little over half-way through all our clients.
