Ubuntu seems running slow!

Hello,

My PC seems running slow:
Code:
OS32 system, Pentium(R)4---2.40Ghz, 1GB RAM, 80GB HD

I am running Ubuntu 11.10 (Oneiric Ocelot) alone in this box, which seems very slow to me. Is this normal?

Compared with my other PC (Running XP) with
Code:
1.99GHz AMD Athlon 3200+, 2GB RAM,500GB HD, XP and Mint dual system,

which is way much faster than this Ubuntu alone box.

I had thought the Ubuntu box would catch up with my XP box. Maybe a little bit slower because of the RAM, but there is big difference there. Thought to expand the RAM to 1.5GB (max volume), not sure worthy it or not.

Then I am thinking to figure out the right way to diagnosis or compare, although I did not compare the motherboard. Googled around, no clear answer about this. Any clue about it?

Thanks a lot!

You need to quantify the slowness, by providing us data.

1. How slow? 2 times slow, 1.5 times slow
2. What is slow? When you open a shell on both and type ls -al, is ls running slow?or maybe not

Thanks!
Code:
1. How slow? 2 times slow, 1.5 times slow

That's the part I was wondering if there is a way to do it.
Code:
2. What is slow? When you open a shell on both and type  ls -al, is ls running slow?or maybe not

Generally, when I try to start terminal console, it takes 3~5 seconds to get the console:
Code:
yifangt@home:~$

Never in a flash.
When I start firefox, it takes about 10 seconds. Starting other applications like "update manager", "System settings", takes more time. Especially to start "Ubuntu Software center" it seems forever. Another example, when I clicked "Preview Post " of this reply, it takes long time (5~10 sec) to see the preview. However, "ls" is running quite normal to me as I never notice any hesitation once I am in the terminal.
Thanks for your diagnosis again.

Sounds like memory/swap related. Post output of

Code:
free -m

from both.

yifangt@home:~$ free -m
Code:
             total       used       free     shared    buffers     cached
Mem:          1002        921         80          0          3        126
-/+ buffers/cache:        791        210
Swap:         1022        710        312

and from the other *faster* machine as well, i.e. output from "free -m" - thanks.

So looking at the above output, it looks you are using swap, which could be why it is slow:

Code:
Swap:         1022      710       312

Also post output from cat /proc/swaps

Code:
                    total       used       free     shared    buffers     cached 
Mem:               1948        610       1338          0          95        289 
-/+ buffers/cache:  225        1722 
Swap:               1160        0        1160

By the way, this PC has Dual system as Linux-mint and xp. The slower one has just Ubuntu 11.10 only. Thanks.
