Hai all,

I have a system with dual boot options(Windows/Linux)

I upgraded my RAM from 128MB to 256MB. Now the system is working fine

in Windows...But in linux..its very slow...(with 128MB it was fast).

I opened the system monitor and found that it has recognized the

upgradation. What was surprising was that with only the system monitor

the memory consumed was 220 MB...and the swap memory used was 0.


And the system is damn slow...


What are changes i should make..?


Thanks in advance,
ARK.

Sorry i forgot to mention that I am using red hat Linux 8.

there might be a problem with your motherboard. see the memory.txt file in your documentation-kernelsource tree.
try adding mem=[32...to 256= amount of mem] to your linux bootup to see where it's starting to have problems with caching and eventually don't use the memory above that. instead build a ramdisk and use it as swapfile.
i asume that that is quite an older motherboard, so it might be no bad idea to get a newer (older) one.

can u tell me where is this file.....memory.txt in the hierarchy

Thanks ..

if you've the source of your kernel on your system you'll (usually) find it under /usr/src/["linux" or "your kernel version"]/Documentation/memory.txt

if you don't go here: (remember: man and google are your friends;-)

Lots of RAM usage is not a bad thing. Try running 'top' from a terminal window to find out what is using up your CPU; that might give you a better idea of why things are slow. Both these issues are discussed in further detail under the wiki FAQ - Linux problems.

I strongly doubt it's anything to do with your motherboard, especially if your system monitor is seeing all of the RAM, and most of it is actually being used. Look for other causes first: running services, cron jobs, too-graphic-intensive window manager, wrong or old video drivers, etc.
