2010.0 - everything running slowly [solved]

Recommended Posts

Just a curiosity. Since everything is running slowly in my new 2010.0 x86_64 KDE clean install, I was wondering if the memory usage could be part of the problem. I found the following commands on the internet, and I was wondering if you could tell me if my 4 GB of memory is being used correctly.

 

Thanks,

Kieth

I find that strange, are you sure it's a 64 bit install? Reason I ask is because it looks like you only have 1GB of ram accessible:

 

total used free shared buffers cached
Mem: 1001 973 28 0 18 340

 

On mine:

 

[ian@esprit ~]$ free
            total       used       free     shared    buffers     cached
Mem:       3677184    1380936    2296248          0      48420     676516

Easiest way is do:

 

uname -a

 

if you see anything other than x86_64 so likely i686 or similar, then you are running a 32 bit distro, it must say x86_64 if it's 64 bit, here's mine from CentOS 5 x86_64 so you can compare:

 

Linux esprit 2.6.18-164.6.1.el5.centos.plusxen #1 SMP Wed Nov 4 10:10:32 EST 2009 x86_64 x86_64 x86_64 GNU/Linux

 

if not similar, then it is 32 bit distro installed.

I'd say: Either you have the wrong kernel installed (by accident and more likely) or the default kernel has a bug (which would be nasty).

:woops: After reading what Ian and Arctic said, I had doubts. I was sure I had I installed a 64 bit system:

 

[kieth@host-001 ~]$ uname -a

Linux host-001.homenet.telecomitalia.it 2.6.31.5-server-1mnb #1 SMP Fri Oct 23 01:19:00 EDT 2009 x86_64 AMD Athlon 64 Processor 3000+ GNU/Linux

 

and I had a hard time believing I had installed the wrong kernel, so . . . I opened my box and I found my error. It's called an OE (operator error!). I only have 2 strips of 512 memory installed! :weird: Sorry. I guess I was only hoping to have 4 GB instead of 1!

 

The fact that I was convinced I had 4 GB is the reason why I wanted to install a 64 bit system!

 

Oh well, so much for pride. After this, who can have it! :cheesy:

 

Now I guess I can alter my original question. The slowness of my system, could it be caused from the fact that I ONLY have ONE GB of memory? When I talk about slowness, I mean, for example, the mouse sometimes moves in a "jerky" fashion, switching desktops takes too long, and it takes longer than before for a menu to pop up. I do usually have at least 3 programs up and running at the same time (OpenOffice, Firefox, and Thunderbird). I will often have more, too. I did not have this problem with 2009 Spring - 32 bit.

 

Thanks (and sorry for the OE!),

Kieth

1GB is perfectly fine for normal desktop use with Linux.

 

Check if you system is swapping a lot:

 

# free
            total       used       free     shared    buffers     cached
Mem:       2073680    1999788      73892          0      94588    1103992
-/+ buffers/cache:     801208    1272472
Swap:      4008208        268    4007940

 

See if the used swap value is high.

 

Also what DE where you using with 2009.1? Gnome, KDE 3.5, KDE 4, XFCE, LXDE,...?

You look to have 1/2 meg working there Kieth.

Either you have one stick of ram that has gone bad or its not seated correctly is what I would think.

That is strange, your first post shows 1GB and your last one shows 512MB. As silversurfer says, when you took it out it probably didn't get seated correctly. I'd get onto it immediately, because if that chip moves when your computer is switched on, it'll short and then it'll blow. I had a soundcard do this when it worked loose from it's PCI slot.

Well Ian, you're right. It looks like my memory strip burned out. I will try again later, but even when I switch the two strips, the computer will not start, but "complains".

Well, it is quite possible that your RAM has just reached its EOL (end of lifetime). Run e.g. a RAM diagnosis-tool like Memtest in order to check for defective RAM. The even more unpleaseant scenario would be your motherboard slowly reaching it's EOL.

Are you saying the good bank of memory that you had will not boot now? Have you tried it with just the one bank of memory in?

If either of the above questions are yes, it is looking quite serious I'm afraid to say. Let's hope not.

Whew, I got it fixed. After I had checked the memory strip, it was registering only one strip instead of 2. The computer would boot on the good one, so I switched them around and put in only the bad one, and the computer wouldn't boot up. So I rigorously cleaned the contacts on the bad strip, and that solved the problem!!! :party0044:

Thanks for the help,
