Lenny installed -- System slow now

shinukl1 · 03-10-2009, 11:44 AM

Hi..

I had been using debian4.0 and now did a fresh installation of Lenny.
Etch was working perfectly fine for me. But lenny has left me with a
slow system. Video is framing , sound breaking in between (only with video),
like more IO wait if i open or close a window.
System is working like having a low RAM ( mine is 1GB ) .
Sometimes scrolling in iceweasel and even switching to a new tab takes time ..

Some process is claiming all your CPU time. Run the top command in a terminal to find which one it is.

You could also check the amount of memory detected and how much is used/free by running the following command:

Code:

free -m

The output will show you (in megabytes) how much RAM is available, used, and free. That will help you determine if all of your available RAM is detected. Since you only have 1GB to deal with, I suspect all of it is available to the system.

You may have something eating up all of your available memory. A quick way to see what is using the most RAM at a given moment is to start "top" (from the command line) and then press the "M" key (upper-case) to sort the output by memory usage. You can also sort the output by CPU usage by pressing the "P" key (upper-case).

While you're in top, it also displays all available/free/used RAM in the output.

Hope this helps

Thanks ...

I got that Xorg is taking my CPU time most.
I think i solved the problem related to browser and playing video
by editing the xorg.conf file after some googling.
I added the line

Option "AccelMethod" "XAA"

under Section "Device".

But still one problem remains. Copying files from local network is verrry slow for me.( ofcourse after installing Lenny)

Here some stuff that might accelerate X further, especially RenderAccel and composite enable.

Code:

Section "ServerFlags"
    Option         "Xinerama" "0"
EndSection

Section "Monitor"
<snip>
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce 8400 GS"
# lugo put in next line.
    Option         "RenderAccel" "true"
EndSection

# lugo put in next block.
Section "Extensions"
    Option         "Composite" "Enable"
EndSection

Thanks ... But any idea regarding why my copying from LAN is so slow ??

This is my ifconfig output :

No idea really, although shouldn't it be 100MiB or something? Question for the networking boys and girls??

That is amount of data not speed, Otherwise my 100 MB NIC is way overcloked as those numbers are in the Gib range on this PC

take a look with ethtool ..

Code:

ethtool -i eth0


ethtool eth0
