Local disc copy at 10MB/s! What could be the problem?

view story
linux-howto

http://unix.stackexchange.com – I am running a Debian 6.0.6 (before you ask). I have a regular desktop computer, nothing fancy... but when I copy a file using nautilus I am getting 10MB/s copy speed and the system is completely stuck! I did some reading and executed hdparm -tT /dev/sda with the following output: /dev/sda: Timing cached reads: 2428 MB in 2.00 seconds = 1214.07 MB/sec Timing buffered disk reads: 274 MB in 3.01 seconds = 91.05 MB/sec So in theory my dist is a lot faster, but in reality it is working very slow. Any ideas what could be the problem? or at least how to search for clues? (HowTos)

Stories similar to Local disc copy at 10MB/s! What could be the problem?

I have two disks, SSD (Samsung 830 128GB) and normal HDD (WD 1TB) and Ubuntu 12.10 installed.AHCI set in the BIOS. I have a problem with extremly slow copying in all directions (Samsung->Samsung, WD->WD, WD->Samsung and Samsung->WD).

Recently my Debian Linux server has been experiencing slow web server response times.

I just installed a new Intel 330 60 GB SSD into my HP Mini 2140 laptop.

But it's not going as fast as expected and my hdparm results aren't looking very good compared to SSD benchmarks at:

My results and info are below.

hdparm results:

justin@justin-HP-2140:~$ sudo hdparm -Tt /dev/sda

/dev/sda: Timing cached reads: 1130 M

Hello

I have an Asus 1215b and I have changed the HDD with an SSD Intel 330 Series 120 GB. I am using Xubuntu 12.4.

The problem is that the netbook is moving slowly.

Determining Disk Speed 32 weeks 2 days ago

Hi,

I went to a computer store and the salesman sold me a SATA cable and told me that all SATA cables are the same. Another salesman at a different store told me a cable rated for SATA 2, which I bought, MIGHT work as well as one rate for SATA 3 but it is not guaranteed. I decided to run a speed test on my SSD drive to check the results.

I am having trouble resuming from hibernation using TuxOnIce method. The thing works, but in a very strange manner. Here's how it looks:

1. Computer boots and finds resume image and starts resume. It reads image from disk (takes ~10 seconds) Reading kernel & process data... Atomic restore. Doing atomic copy/restore.

2. Resume pauses for about ~30 seconds displaying above message.

Hi.I'm having a really nasty problem with my laptop.
