I would like to know the memory usage of my computer.
I am not able to decipher the /top/ command:
top - 20:19:14 up 89 days, 2:15, 5 users, load average: 0.11,
0.08, 0.05
Tasks: 116 total, 1 running, 115 sleeping, 0 stopped, 0 zombie
Cpu(s): 8.8% us, 0.8% sy, 0.2% ni, 90.2% id, 0.0% wa, 0.0% hi,
0.0% si
*Mem: 2593592k total, 1932912k used, 660680k free, 17956k
buffers*
In another system the top command output the following:
Processes: 102 total, 3 running, 99 sleeping... 261 threads
20:47:33
Load Avg: 1.03, 0.58, 0.34 CPU usage: 23.6% user, 8.5% sys,
67.9% idle
SharedLibs: num = 229, resident = 58.2M code, 6.12M data, 17.8M LinkEdit
MemRegions: num = 16425, resident = 469M + 16.7M private, 225M shared
*PhysMem: 331M wired, 407M active, 1.46G inactive, 2.18G used,
2.32G free*
I am puzzled. How a system that is idle can use 2.18 GB (the sum of
wired, active and inactive) out of 5 GB? Am I reading wrong the top command?
What is a wired memory? Why doesn't the inactive memory go to the free?
Thanks
