Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I upgraded my RAM from 128 MB to 256 MB on intel 810 chipset,
i added one more 128 MB RAM,
My system is running on LILO boot loader, for both red hat linux and windows 98.
Even though both Linux and Windows detected 256 MB RAM,
Linux performance went wery bad, even it is taking more time to boot linux !
What may be the problem?
It is must to increase the swap sapce if RAM is upgraded? if not needed why the system perfirmance went down?
How can i increse swap partition?
Do i have to configure any .. if I upgrade RAM for linux, because it is not the case with windows
that dd command was for making a swap file.
So how do i extend a swap partition, The quesiton remains the same, Can you let me know why my PC performance went down even after detecting upgraded RAM. Of course swap partition is not extended. do i have to make any conf changes?
and one more doubt here guru
How does it differ Creating a Swap Partion and Swap file,
Did you install the same type of RAM? If that is all you did to the PC you could try removing the RAM and see if the performance improves.
A swap partition is faster then a swap file. How big is your swap partition now? The free command will show how much swap space is being used. If your not using much then increasing it will not improve performance.
linux can use multiple swap partitions. The easiest method would be to create another partition. Use mkswap to format and add a line to the fstab. If you have your entire drive partitioned it would be a task to resize existing partitions just to resize your swap.
The dd command just copies raw binary data to a file / device. And in this case it is just coping all zeros. And since your trying to copy 512mb to 250mb parition the command runs out of space.
Resizing partitions will be much more of a task then I think you ready to tackle. Like I said if your not using any existing swap space then adding more isn't going to help. The program parted will resize existing partitions. The easiest method as described above would be to add a swap file.
The new RAM should be of the same type and speed. If there not the same speed then it should be faster. New motherboards are more sensitive to the different manfactures memory and so check with motherboard manufacture for recommendations.
Like I posted before remove the new memory and see if the speed is back.
Distribution: RH 6.2, Gen2, Knoppix,arch, bodhi, studio, suse, mint
i use no swap, and my system runs about the same,
no matter the amount of ram. sometimes i need some
swap for something, and i add it then. i just think
something's messed up with the ram or motherboard,
who knows, and the swap doesn't have anything to do
Try swaping the new RAM for the original RAM stick. If the computer runs slower then you might have the wrong type RAM. If it runs just as fast then since the RAM sticks are not from the manufacture then they might not play together or you might have an issue with the second RAM slolt.
I too dont want to use swap , linux does it
I want to make use of my full RAM,
Here problem is System is detectiong the RAM, but performance went down , if i reinstall linux i think the performance will boost up, but reinstalltion is not the solution, so better i try with swap file only best option i have!
Try swaping the new RAM for the original RAM stick.
please let me know how to do this . . ?
=> If the computer runs slower then you might have the wrong type RAM.
May be they are from didffernt make, they are doing good individually, may be in this case two swap partitions will do !?
I forgot to ask how many memory slots you are using? I had assumed that you had one 128mb memory stick. So by installing the new RAM in the slot where the old RAM is located this will verify wether the new RAM affects the speed of the PC.
If it runs as fast as you think it should then place the old RAM in the second slot. If not then verify the new RAM is the correct speed as the old. If the system runs slower with the new RAM in the 1st slot and the old in the 2nd then you might have a compatablity problem between the two.
I had read were some motherboards with three slots did not work with RAM in the third slot.
Look at the output of the console command free. If it shows zero or close to zero for swap usage during your normal computing activities then adding additional swap space will not improve performance.
