Home Why linux always shows high memory usage?

Why lunux allways show high memory?

E-mail Print

Have you evenr wonder seeing high linux memory utilization? Even if you not running any memory intensive appliations, top, sar allways report above 90% memory utilization. Its because linux uses free memory pool for caching disk blocks, so most of the free memory used for filesystem cache. But it freed up dynamically if an application requires real memory. You can get actual memory usage b y using command free.

$ free
             total       used       free     shared    buffers     cached
Mem:      28817368   26486372    2330996          0     600588   10293964
-/+ buffers/cache:   15591820   13225548
Swap:     16390128      17080   16373048


Sargraph is designed to report real memory usage, it wont report the memory used by buffers and cache. So it will give you the actual usage trend of memory.

An intriguing discussion is worth comment. I think that you should write more on this
subject, it may not be a taboo matter but typically people don't speak about such topics.
To the next! Cheers!!
