Linux defrag memory

nop ,

but what you meant by used memory ??

does it show cached ??? cached is always good.

can you show me the out put of

free -m

and tell me which is one bugging you

If you want to know the amount of used or free memory, you must always read the line

-/+ buffers/cache:

of the free command.

i know i could see the memory usage but i just want to know if there is a way for defrag

no you cant defrag memory uses


may be we can help you to find out which process is eating your memory and further but not defrag

i know it is a php site :D
but i do not know which module is encountring this :(

then it would be Apache issue

php works with apache...

whats the outpu tof

free -m

and

ps -auxf | sort -nr -k 4 | head -10

Even if there was a defragmentation tool (there isn't!), it wouldn't change the memory consumption: only the layout of the chunks would change.
However the layout doesn't matter, because the mapping to the real memory chunks is done by hardware anyway. There is no performance penalty. It's handled by the MMU (memory management unit) of the respective processor.

Well, he asked for information on the memory fragmentation. I'm not particularly keen on the points (are they good for anything on the receiving side ???), but that was, what he asked for and he has been answered.

Thanks for detailed description
