Computer EXTREMELY slow, but shouldn't be. HELP!

Recommended Posts

Sorry about the duplicate untitled post, I'm not sure where my mind was.

 

 

Hey all, I'm having some annoying problems with my work machine.

 

Specs:

NEC Powermate 2000

PIII 600

128 MB Ram

18 GB HD

 

The machine is an all in one machine with a flat panel monitor built into it. The monitor base houses all components.

 

Problem:

 

This machine is slow!

Very very very slow!

 

I'm currently running Ubuntu Warty Warthog, but I previously ran SuSE 8.2 and Yoper 2.1 on it with the same issues. It used to have windows 98 on it but I formatted it off.

 

The problem did not occur in windows but all linux distros run extremely slowly.

GNOME is unbearably slow.

WindowMaker even is slow - 2-4 seconds just to open the Applications menu by right clicking on the desktop. Up to a minute to switch between Firefox and Openoffice, which is extruciating.

 

What could the problem be? I enabled Unix large disk access mode in the bios but it didn't help, neither did enableing and disabling DMA. There is a 800 MB swap partition also...

 

Anyone know why this machine is so slow?

What do you mean by slow? As in it loads slow? Graphics are slow? If your graphics are slow you might have your x config'd wrong...if it is running very slow try running in a non graphical mode(you can kill x by hitting ctrl alt backspace). See if it runs slow there too. If it does most likely the way you are installing is correct. I am not too familiar with the distros you listed but any distro should be able to run pretty well at the command line in a non graphical mode.

Everything is slow. Typing, everything. But only when I'm in a windowed environment. Everything works fast in command line only though. Still, I run Ubuntu on a much lesser system at home, and it works quite fast. Here, clicking on the Applications menu can take up to a minute for disk activity to cease and then the menu finally pops up, then it works fast until I open a program from one of the submenus. These can take up to 10 minutes to load, especially firefox and openoffice. But even nautilus takes 30 seconds or so. The performance is equally bad in minimalist window managers, WindowMaker, Blackbox, etc. Moving windows is smooth, once I can grab them (takes a sec but then they move fine). It just seems like everything is proceeded by a long delay full of hard drive activity.

Two issues right off the top. An increase in ram would be useful, as 128 mb is bare minimum to run thse distros. 256 would be much better.

 

Secondly, is the swap space being utilized at all? Is it in your fstab file?

 

Finally, in the bios, is PNP OS disabled or off in the bios (PNP configuration)?

when it's being slow, can you open a terminal and type

[size:4][tt]cat /proc/interrupts[/tt][/color]

then count off three seconds and type

[size:4][tt]cat /proc/interrupts[/tt][/color]

once more, then post the output here?

Fstab shows a swap partition, and it looks normal

 

I run the exact same distro on a Compaq Armada Laptop

PII 266

64 MB Ram

8 GB HD

and it works much better than on this machine.

 

and here is the stuff you asked for martouf

hmm..

 

[size:4][tt]$ dc

705822926 705817760 - p

5166[/tt][/color] timer interrupts processed.

 

Not that many other interrupts between the two interrupt count samples.

Guess this machine is networked via ndiswrapper, because eth0 didn't have any interrupts.

 

what version of ndiswrapper are you using?

 

where is the display driver? it should be shown hooked into one of the interrupt lines.

 

thought you said the machine runs slowly when X is running and not

so badly otherwise...

 

would you provide the output of [size:4][tt]free[/tt][/color] ?

we'll be able to see how the system memory (RAM + swap) is configured.

Yep, both my older laptop and this machine are using a WPC54G wireless card with ndiswrapper. I'm sure its a recent version as Ubuntu comes with in in the kernel of as a kernel module.

 

Not sure why there isn't a display driver listed, I was running Open Office and Firefox at the time in X so ....

 

What do you mean the output of free - is it a command I'm not familiar with? smile

you ought to find the ndiswrapper version information

in the output of [size:4][tt]dmesg[/tt][/color].

 

try: [size:4][tt]dmesg | grep ndis[/tt][/color]

 

for memory config, there's [size:4][tt]free[/tt][/color] and [size:4][tt]procinfo[/tt][/color].

procinfo gives a nicely concise memory and interrupt report.

free gives just the memory report.

 

( raw data may be obtained using:

[size:4][tt]cat /proc/interrupts

cat /proc/meminfo[/tt][/color] )

dmesg | grep ndis

completes with no output.

 

I should't be using an accelerated driver as this card doesn't support it.

 

Output of free is:

Swap seems smaller than I thought but still should be fine I'd think

huh.. really? here's what I've got on my test system:

 

[size:4][tt]$ dmesg | grep ndis

ndiswrapper version 0.6+CVS loaded[/tt][/color]

 

(second command run as root, many distros don't allow regular

users to read /var/log/messages)

 

[size:4][tt]# grep ndis /var/log/messages

Apr 21 14:58:33 testsys kernel: ndiswrapper version 0.6+CVS loaded[/tt][/color]

 

Ok, no accelerated display driver. confirmed. good - it had the

potential to be the source of the problem. unlikely, but potential.

 

the swap config looks OK. Nothing looks bad there.

 

the one big difference between your system and mine is the really

large number of LOC interrupts. Mine is 0. Even after millions

and millions of timer interrupts. it's the local interrupt counter

in the APIC. your APIC must be on.

 

hmmm..

 

have you (or would you) try booting with "noapic" ?

booting with both "noapic" and "nolapic" ?

gidday ppl

 

I would almost place a bet on martouf's last two lines. booting into "noapic"-mode could indeed solve the slow response times (I dimly remember this issue from my Mandrake times).

 

good luck, and if it helps, buy martouf a beer smile

I booted with noapic and no|apic

 

did I do something wrong here?

I went to the grub menu, hit e to edit the boot option

 

after kernel blahblah.386 ro splash

 

I added noapic and no|apic

 

then hit b to boot

 

Did I mess up or do it wrong?

the letter you need to use (in ITU phonetics) is "Lima"

 

Alpha == A

Bravo == B

Charlie == C

Delta == D

Echo == E

.

.

and so on..

.

.

Lima == L

 

nolapic ::= Nancy Oscar Lima Alpha Papa India Charlie

 

ok? smile
