My ubuntu all of a sudden started loading and moving slow. It is acting like when i had a lot of spyware on my windows version. Surfing is moving almost like dialup. What might be the problem?

Hi and have you installed, updated or added any hardware? What are some system specs? Just asking questions to maybe narrow down the issue.

1) Or have you installed,or updated any software after which your computer started running slow?

2a) Appliations > Accessories > Terminal

then type in this code:
top

2b) If you prefer a GUI to the Terminal, then do this: System > Administration > System Monitor

Yes I have always accepted the updates as they come. I thought I was supposed to do that. I get updates about twice a week and yes I accepted them. I did the top command and i got

Could you repost the output of top using the code tags,You can click on the # sign in the advanced editor. You've got something using about 95.7% of your cpu's output, but without any formatting it is hard to tell what it is.

1) Applications > Accessories > Terminal

Then paste or type in this code and post the results here:


uname -a2) What version of Ubuntu are you using?

3) Boot into GRUB (hit esc when it says to in boot up), then go choose an older kernel if you have one. Next check top again and see if the problem is still there or not.

4) There has been this problem reported with some versions of kernel 2.6.9.

Just a stab in the dark here:
I recently installed ubuntu (hardy) on a computer and made the swap partition to large. The computer then took a lot of time to do anything and the hard drive was noticeably spinning more often. I would defer to the opinion of some of the other guys here, but perhaps it could be this problem you're experiencing (though if you let ubuntu do the partitioning for you during setup, or if it's been a while since you installed this shouldn't normally be the problem..)

For example, in your output from "top" earlier, your swap partition is 1919728k:

Swap: 1919728k total, 0k used, 1919728k free, 340184k cached

My swap drive, for comparison, is 497944k for a primary ubuntu partition of 55GB and 512MB of RAM.

i am very confused now. what can i do to correct the problem? i partitiioned the harddrive myself. does it sound as if i have too much on my harddrive the linux part? i dont have much in my documents. i have 12 gbs left on my harddrive. on the linux part the xp part i am sure has much more room.

Bump - a large swap partition *could* be your problem but I'm not sure how to say that it is definately so.
