Ubuntu :: Performance Difference Between 4 GB And 16 GB USB 2.0 Hard Drive
May 26, 2010
I am currently running Ubuntu 1004 but I have the OS installed on a USB 2.0 hard drive because my normal hard drive caved. However I am having problems because there is a SEVERE lag on my system. So my question is if I buy like a 16 GB USB 2.0 and use that instead of my 4GB one will it make a performance difference? My laptop is the Dell Latitude D600(1GB RAM, 1.6 Ghz Processor, ATI Mobility Radeon 9000) and I AM NOT in the market for a new laptop or a new hard drive. Edit: What about buying an external hard drive and using that instead of USB's?

if I make more partitions rather than creating single one, will I get more data access performance? E.g Instead of keeping 1,5TB partition, create 5x300MB and keep different data in different partitions? Logically hard drive will spend less time on finding data in smaller partition then in bigger one, right? Is there any statistics for performance vs size?

I am currently using the 32 bit version of Ubuntu on my 64 bit laptop. My question is, does using a 32 bit version on said hardware reduce its performance (i.e will battery life be reduced, system be under more load, etc.)?

Now, I'm ready to run my program, and my code is based on 32bit version. So I run the program on Ubuntu 9.10 32bit. And I got running time for 48s. But that's a bit slower than I expected; the program has bunch of File I/O processing but the result(48s) just doesn't make sense compared to given initial data set. So I just run the same program and same initial data set on Ubuntu 9.10 64bit ver. Then, bang!! it took 1.4s to finish the job.
Do you have any thoughts what kind of fact might make this significant difference? The differences b/w those two OS are "32 vs 64" and 32bit version has Java SDK, Eclipse, Apache2, Mysql, PHP, CGI, and python. We-server service is running but because I'm not really running web server. Did the result come from these background programs?
-- I tested it on the both OS in the same situation as possible as I can.
(reboot->test)
-- BTW 64bit one doesn't have those programs. I just installed on my external hard drive, so it's literary PURE one. (32bit one also in the same HDD)
-- I run these Ubuntus on VMware

I have a 64-bit computer but 64-bit distros have been giving me huge problems when using 32 bit apps or trying to install 32-bit libraries, so I think I'm going to just switch to 32 bit. Will I notice much of a hit in performance? This computer is mostly used for web and games, nothing particularly cpu-intensive (no graphics rendering, etc)

I have installed several different distro's over the last coupled of weeks and have finally as intended come back to 11.4. Last time I installed it my pc was fitted with an older nvidia card and I installed a newer 200 series and got it to work with X11 using the nvidia driver. This time I did the install with the new card in and things haven't gone the same way. I have finished up with the os drivers on my system, nouveau and "swrast (No 3D Acceleration) (7.10)". Performance wise it's way way behind the nvidia driver.
Glxgears for instance runs at under 1/2 the speed even at a lower resolution. I suppose I could still configure to suite my monitor but given that difference in performance would you? I have done what I can easily do with repositories but no signs of nvidia drivers. I can download one as I did last time but from what I have read previously the above drivers may mean that I have to recompile the kernel. A simpler solution might be to re install with my old card in. Can't say I'm too keen on either option. Some distro or the other had a driver helper and installed the nvidia one perfectly.

There are 3 channel DDR-3 RAM kits available on market.Would its performance be better than dual channel RAM kit, apart from RAM capacity? I'm planning to build a new box testing server consolidation on virtualizaion running Xen/Vserver/OpenVZ as software. All servers running 64bit Linux OS. My new planning is to get 2 sets DDR-3 1333/1600 4Gx2 kit. I may consider 3 channel kit dropping the total RAM capacity to 6G if it has better performance. Besides can mobo support dual channel RAM also allowing 3 channel RAM to work on it without sacrifying performance?

My parents bought a new hard drive for a laptop that I've owned for several years. It's much larger than the current one, so I plan on splitting it up to dual boot it with Ubuntu.I have no problem with partitioning a drive (I always keep a LiveCD handy), but my question is this: how can I go about moving the existing partition to the new drive? This is a laptop, so I can't simply plug the new drive into another slot.
Also, even if I manage to move it, will Windows still work on the new drive in a larger partition? I've had this laptop for quite a while, and I've lost the recovery discs that came with it a long time ago. I also have a lot of software without CDs to reinstall them with. This makes not reinstalling Windows a high priority.

Trying to install Fedora 12 using the 6 CDs. Trying to install on an older x86 box.Problem is that when detecting my hard drive, Fedora 12 recognizes it as a sda hard drive instead of hda hard drive. I have no SCSI connected to my computer what so ever. It's an old fashion PATA Western Digital hard drive.If I proceed with the install, Fedora 12 only installs 200MB of the OS from the first CD only. No options for additional software or anything.

I have a laptop with only 30GB storage and I want to install Lubuntu in virtual box but Lubuntu needs 5GB of storage space which i dont have. Could i use an external 160GB hard drive to act as the hard drive for the virtual machine without affecting the files that are already on the external hard drive

Ubuntu 10.10 is dual booted but it is my primary OS.
Unfortunately it's on the outer edges of the disk in an extended partition.
This has always bugged me, with regards to read/write performance.
Do my concerns of reduced performance have any foundation? Should i bite the bullet and format the drive installing ubuntu first?
I ran the disk read benchmark and my read speeds were 100MB/Sec at the beginning of the test to just 55MB/Sec at the end. I have no idea if the position of the test has any bearing on the position of the disk or whether the speed recorded is affected by other factors such as the tests function or simulation.

I have a SATA drive that worked fine. Then I installed two more hard drives into my system. When these hard drives are installed, if I try to access the SATA drive in Linux, it will start lightly clicking and then the drive will become unavailable. If I power on the machine without the other two hard drives then it works fine. What could be causing this to happen? I don't think it's heat because the two hard drives are far away from the SATA drive.

I just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

I just booted one of my computers from a usb drive I had installed Ubuntu 10.04 LTS to, and when I booted it up on that computer, it worked fine. Then, when I powered down the computer and booted it back up to the main hard drive, it booted to the same that my flash drive was running, but my flash drive was not plugged in!! How is this possible? Did it copy itself over my other operating system? There is no trace of it. By the way, that, too, was ubuntu 10.04.

I would like to install Linux Ubuntu 11.04 on an external hard drive - its partitioned and ready for Linux.I've downloaded and burnt the .iso file to a DVD so its all good so far...First of all... is this possible without messing up my macbook? I don't particularly want to break into my macbook to disconnect the hard drive (I read on a tutorial for a previous version of Ubuntu that I'd have to do that... - does it still apply to 11.04?) - as it voids the warranty (I checked ).The reason I ask this is because I had a friend who partitioned their internal hard drive and installed Ubuntu on it. But after installation was complete they couldn't boot up Windows 7 or Ubuntu... and it resulted in them having to clean install Windows 7... - I don't want to end up in that situation
Second... If it is possible to install it without messing up my macbook... - Do I just follow the install instructions but just make sure that where possible I make sure that everything is installed on my external hard drive?...I really need someone to put my mind at rest that everything will run smoothly and that I'll be able to run Mac OS X as usual but also that I'll be able to boot from my external hard drive to run Ubuntu.

I am trying to move a whole bunch of files from one partition on one hard drive to the same partition on another hard drive. Can I mount the same partition (same name, different drives, i.e. /data on /dev/hda1 and /data on /dev/hdb1)and copy those files? Shutdown the server, take out /dev/hda1 and boot up with the new drive and it's /data contents.

I am soon going to have to return my intel ssd for replacement. Therefore, I am going to be cloning the 160gb drive to a 320gb drive to keep my system settings while I am waiting for my new drive. I will not change the size of the partitions to fill the 320gb drive. I'll just change the grub settings if I absolutely have to. After that, I am going to have to clone the 320gb drive back to the replacement 160gb drive. Am I going to have problems doing that since I will be going from a larger to a smaller drive?I typically use Clonezilla with the default settings.
