Unhappy IBM T42 "Extremely, EXTREMELY Slow"


Just bought an "off lease" Thinkpad T42; Ubuntu Jaunty installed; 1 gig ram.

It is so slow that when I finish typing a paragraph, it takes the system 10 or 15 seconds to finish displaying text on the screen (I only type about 50 wpm).

So, I removed 512 of ram, and it helped, but Only a Little.

I then did a clean install of Kubuntu 9: No Change!

This Thinkpad is an upgrade to a PII with 256 ram and RH 8.0 which smoked!

Why is my new Laptop SO PAINFULLY SLOOOOOOOOOW???

Any suggestions for the cause would be So Appreciated!

Thanks much,

Michelle

p.s. - I am hoping that I don't have to donate it to charity

Is it possibly a problem with Ubuntu? Have you tried any other distribution? Are you sure the RAM you're using is working correctly? Is there possibly a problem with the hard drive?

Try downloading some lightweight live distribution like Slax or Damn Small Linux and see whether that works for you. If not, have the hardware checked.

I'd leave the ram there. Check the logs for errors. Put the next line in a terminal
grep -i error /var/log/messages

also check for a swap partition. If your box is 64 bit, get another 1 gig at least of memory
'free' is the command that tells you your memory usage. There may also be driver issues. Try

sudo hdparm -tT /dev/sda and tell us what it says. Here's my output:
/dev/sda:
Timing cached reads: 2094 MB in 2.00 seconds = 1047.51 MB/sec
Timing buffered disk reads: 186 MB in 3.01 seconds = 61.70 MB/sec

The 61.79 MB/sec is the figure.

no error log output, but the second:

/dev/sda:
Timing cached reads: 1198 MB in 2.00 seconds = 598.50 MB/sec
Timing buffered disk reads: 90 MB in 3.05 seconds = 29.54 MB/sec

what do I do next, please?

Have you cleaned the CPU fan? My daughter had been complaining about her Mac mini being slow so I bought her more memory and went ahead and got a larger drive while I was at it. When I got it apart, the CPU cooling "system" was just clogged with dust and grunge. I credit cleaning that out with the major part of her speedup. You might check to see if CPU throttling is in effect.

I'm guessing that T42 is about 5 years old and 32 bit. 29 MB/S is slowish, but OK.
The likely things to slow it are: Slow disks (More or less eliminated); Poor choice of drivers; Low cpu speeds due to overtemp or some other setting; Massive video issues, This is by no means an all inclusive list.

Are you using a compressed disk or running off a CD?
Can you check your cpu temperature? over 70 degrees kills action.
You might run memtest86 on it? http://www.memtest86.org
You might take a look in /var/log/Xorg.0.log for video hassle (Falling back to ...)
Let us know how you get on.
Then Post the output of 'cat /etc/mtab'
