High memory usage in 8.10
Hi all,
I am wondering why my ubuntu computer has such excessive memory usage. The command free returns
I see that ~500 MB is cache, but that still means that 1.4 GB is being used and I'm not actually doing anything.Code:total used free shared buffers cached Mem: 2056836 1929064 127772 0 35408 493736 -/+ buffers/cache: 1399920 656916 Swap: 4883140 2144 4880996
The print out from Top is
If I add up all the memory usage, it isn't anywhere near the 66% indicated by free (used - [buffers + cache]).Code:USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 4100 900 ?
