Why is my Redhat Linux soo slow
 

Hi .. I have had linux for about 6 mnths .. stilll a newbie though . didnt use it at all .. I changed to windows xp so i performed a linux rescue .. with the help of a friend .. now my linux is so excruciatingly slow .. also it hangs up and whatever i click never loads .. finally the only soln is to logout .. and then when i click on logout it completes all the tasks i had clicked on and logs out .

if this is of any help .. I also have another problem .. on my grub screen there are 2 names written for linux

Redhat Linux - 2.4.20 - 8bigmem
Redhat Linux- smp - 2.4.20 - 8smp

why are there 2 options .. I have noticed both lead to the same thing .. the settings i made on one are effective to the other .. how can I remove one of these options so I jus hav two options windows xp and linux on the grub screen

Thanks .. This is a big pain right now . I hope someone can help moi

hi there

these two options are basically two difernmt kernels
smp-symm. multi process
bigmem-kernel with big memory support
u need to use a generic kernel,if u do not have multiprocc,or u do not have memory>4GB


also regarding ur slow system problem
u need to check for bad blocks
checlk for services whcih u do not require

or compile ur own kernel(the best but tough option)

regards

Running it in smp mode on a 'non smp machine' could cause slowdown and crashes also.

I think you can change the bootup options directly from grub's shell 'try typing grub at your sh'.
'info grub' should also have some information on the subject

Since I dont have more than one pro and i have >4GB memory .. I need neither of the modes .. what do I do so tat grub shows me jus one option

Thanks ..

hi there

u can see what kernels u have installed from

rpm -qa|grep kernel


then u can remove that by



rpm -e kernel-smp

do not remove the generic kernel

regards

kernel-bigmem-2.4.20-8
kernel-source-2.4.20-8
kernel-smp-2.4.20-8
kernel-pcmcia-cs-3.1.31-13
kernel-BOOT-2.4.20-8
kernel-2.4.20-8

which one shld i remove ..

hi there

u can keep these

kernel-2.4.20-8
kernel-source-2.4.20-8(kernel source code,req. if u want to compile ur kernel)

and remove the others

regards

he said he HAS >4gb memory - won't he need the bigmem support?

hi there

i got it little messy....

both things have been stated above

"i have >4gb memory and i need neither of the modes ."

i think this needs to be confirmed ,does he have more than 4 gb of RAM

regards

hi .. how dumb am i !!!! sorry I dont have 4 GB Memory .. far from it !!! stupid of me to not to check what i typed .. <4GB i meant ..

Type the command "top", it shows you what programs are using the most resources... maybe some of them shouldn't be running.

Then this should suffice quite well :)

hi that

good that is sorted out now!!!!
