General question on memory shown in top
I have one question in general on TOP memory,
with top when i get the bellow data (at system level) , how should i read 'Used' memory (Mem: 49371432k total, 917120k used, 48454312k free, 24256k buffers). Will it consider all Unix processes consumption (RES/VIRT/SHM), if yes which memory will it consider? Once process stopped, will this count come down?
Or it is just memory considering whole system physical memory used by all active processes? including kernal persistent memory (like Shared memory created by application, kernal persistent Qs etc..) Or anything else considered here.
Also how to read the relation in data shown in "MEM:" and "SWAP:" lines of top out put.
Thanks In Advance
