Ram being eaten by linux?
This is wierd, I just installed a 512 ram into my computer making it 1gig ram... now before i used to run my programs and it'll be using 400 megs, but nowit';s using 800.... is it like it even matter if i get more memory? seems like it ;\

hi
just read somewhere in the forum that u need sometype of bigmem support for ur system in the kernel here is the one just read this one through http://www.linuxquestions.org/questi...hreadid=223835 regards |
thanks
hmm that whole thread went way over my head i'm afraid of compiling a kernal, firstly, i don't even know where to start, what it's meant for and how to do it :( |
hi
i hav ben using redhat /fedora and here i have a rpm package for a kernel which gives the support of bigmem in the kernel u r using suse,and these rpm packages won't run for u so u need to compile ur own kernel have a look in the "newbie guide to kernel compiling by Dr Ozz" in the linux general section in this forum regards |
so using that guide will and compiling a new kernal will fix that problem?
|
Don't worry about recompiling or anything. The highmem is needed for greater than 1 gb only. At most, you'd lose the use of ~24mb of ram. Also, don't worry about "execessive" ram use. Only worry if the swap is being used to much.
P.S. with that much ram you'd be able to run knoppix completely from ram. It will run sooo fast. |

i too had the same opinion but the thread i mentioned above has it all go through all of it. i cannot test this because i do not have so much memory and minm may be u can see by using "top" which of ur process is consuming the most regualrly regards |
I thought this is normal, Linux tries its best to make use of the available ram. What's the point of getting more ram if you don't want your system to use it?
|
ok, im confused, what do i do, download the kernal from kernal.org, and compile it, or do i just ignore it?
i mean, i want it to use it, and i'm kinda annoyed how it slowly eats up my ram... what do i do? What kernal supportes 1gig ram? |
ignore it, this is normal on a linux system, it's just being claimed by the kernel for future use. as long as it's not swapping to disk excessively, and there is no system slowdown, there is no problem.
|
ok thanks :)
|
BTW what does commands top or free show as total memory?

1036600

You have to recompile your kernel if you have more than 896 megabytes to get all the megabytes back that you installed. All you need to do is make sure you have the source code version that is the samve kernel version you are using. As su or root you should do "make oldconfig" under the kernel source directory (usually its /usr/src/linux). Then you can type either "make menuconfig" or "make xconfig".
Linux uses some memory for buffering, caching, and other things. Windows users gets confused how memory management in Linux is handled. Quote:

i'm soo confused right now, people say don't worry but people say recompile
*mind blows up* hehe |
