Why Is My Computer Slowing Down?

[DLX]

  N4RPS you must do lots of recalls
Thanks again all help 

I had this before so looked at my notes. URL Blacked out FF 36.0.1
So did screen shots may help someone then just text.

Make new Tab

Copy about:config past into URL address box hit Enter


This will load don't worry click button. I'll be careful, I promise


Search for gfx



Then look for gfx.xrender.enabled click on change value from True to False


Now restart FireFox for setting to work.

Hello!

I with BT but talking to a Indian help desk is pain full I don't hear to well just add to the problem.

I get slow here sometimes, too. I notify AT&T, they remotely check my line, and the speed comes back.

I'm not a big fan of outsourced customer service, either. I just keep calling back over and over again until I have one on the line who I can halfway understand...

Hi all many thanks for replies 
I read probably tomorrow bit rushed now.

I did do speed test today funny that and was only 14.mbps were I pay for 40mbps down as I'm on fliber to the box not to house I did get 37 38 first couple days.

I with BT but talking to a Indian help desk is pain full I don't hear to well just add to the problem.

Think avj point of harddrive as computer is slow when not on web when just playing music does sound like about to take off!
As said will read full then skim tomorrow.

Many Thanks all 
----------

Linux Lite was the sole OS on this box no Virtual computer. My second drive is new so going make that main dive and that the old disk out could be 15+ years old. Plan to wipe then fresh install of lite 2.2 

I did donate as so much good help many thanks all.

Hello!

An ad blocker, like ABP for Firefox and Chrome, might help speed you up somewhat. You also might make some online speed tests, using speedtest.net or some place like that, at the times when it's slow, to see if your ISP is giving you the speed you're paying for.

In Windows, defragmenting helps, but Disk Cleanup in Windows, and programs like CCleaner, do more - by removing unused temporary files, Windows Update backups, abandoned registry entries, and the like. (When was the last time YOU uninstalled a Windows update?)...

I have had a couple HDD crashes. Lots of noise and a constantly spinning drive are tell tale signs.

@ avj,
Good spot on the detail... I just looked at the "O.K"
I guess a backup & restore to new disk,
assuming it's worth spending on a new disk.?

[avj]

Here is more info on HDD expected lifetime.
http://www.extremetech.com/computing/170748-how-long-do-hard-drives-actually-live-for

In my opinion it appears that the HDD is failing. There are many read errors, over 232 million according to the screen shot. That along with the seek error rate 369 million and uncorrectable errors in 1416 sectors. More about seek errors here:

Hi,

Nothing screams out issues,
Firefox is a bit of a CPU/Memory Hog if you look at the individual items,
and add them up.


From your first post your disks appear to be sda , sdb & sdc

Have you done a speed test recently..??
I use: http://www.speedtest.net/
It's reasonably consistent, and close the BT Wholesale Tester
Unless you are with one of the Fibre Provider like Virgin..

No network slow. Web pages loading & downloading at times slow .  All round seems a bit sluggish

Htop and hard drive tests look OK to me.  It says 30 bad sectors but disk is OK. Is it only online stuff that you are doing that seems slow? If so. Your ISP server or home connection may be
slowing things down which is outside of your control. Other than calling your internet service provider.

I have called and had my ISP provider. Windstream.  Change the wire from my pole to the house because of problems.
My service became a little better after that.

Is any other computers in your house slowing down? Is your computer a dual booter and is Windows slow also?

Have you ran a memtest yet?



memtest should be ran for a few hours at the least for a good ram check.

[DLX]

wow many thanks for all detailed help.
I got plenty to try.
-----------
Right I loaded install gnome-disk-utility








then did sudo badblocks -v /dev/sdx
Checking blocks 0 to 78150743
Checking for bad blocks (read-only test): done                                               
Pass completed, 0 bad blocks found. (0/0/0 errors)

Did get any there then sudo hdparm -t --direct /dev/sdx as don't know unc of drive i.e C:/

Thanks alot

Hi,

Follow avj's recommendation to see if your disk is "SMART"

A few additional things:

To check for bad disk blocks:

Code: [Select]

sudo badblocks -v /dev/sdxwhere x is your disk(s) , like:

Code: [Select]

dave@asus-mini-1:~$ sudo badblocks -v /dev/sda
[sudo] password for dave:
Checking blocks 0 to 125034839
Checking for bad blocks (read-only test): done                                                 
Pass completed, 0 bad blocks found. (0/0/0 errors)
Can take some time depending size/type of disk

To check basic disk access/speed:

Code: [Select]

sudo hdparm -t --direct /dev/sdxwhere x is your disk(s) , like:

Code: [Select]

dave@asus-mini-1:~$ sudo hdparm -t --direct /dev/sda
/dev/sda:
Timing O_DIRECT disk reads: 1530 MB in  3.00 seconds = 509.42 MB/sec

dave@asus-mini-1:~$ sudo hdparm -t --direct /dev/sdb
/dev/sdb:
Timing O_DIRECT disk reads: 332 MB in  3.02 seconds = 110.01 MB/sec

Regarding defrag, this is hotly debated, but Linux "does" fragment,
BUT, the impact on day to day typical users is very minimal.
In high end servers/transactional systems, yes it is very important.

If you want to defrag..??

Code: [Select]

sudo e4defrag -v /<location>where <location> is your disk partition(s) , like:

Code: [Select]

sudo e4defrag -v /or

Code: [Select]

sudo e4defrag -v /home
Finally,
Menu > System > Resource Usage
Is there anything showing that seems to be "hogging" CPU/Memory.?

[avj]

I would suggest installing gnome-disk-utility so you can check the "smart" status of the drive to see if it is failing. The program pulls in a few dependencies but nothing major. After it is installed you go to main>settings>disks when you open the program you should see a list of drives on the left. Hit Ctrl+S to open the smart status screen for the selected drive, and to see the general health of the disk. Hover the mouse over each line in the window to see what that information means. If it shows a "read error rate" value of anything other than "0", you need to take steps to save your data, and start planning to replace the drive.

[avj]

Excessive noise and drive light staying on can be an indication of an impending hard drive failure. If at all possible you should backup anything that you don't want to lose.

No network slow.
Computer making alot noise sounds like it going to tack off. hard drive spinning
Web pages loading & downloading at times slow
Programs opening at times
load Google maps to Satlight moad

All round seems a bit sluggish

[AustinTexas]

What process do you believe is slowing down? Loading programs?
