It have been noticed that memory
usage is 64% which seems higher.
Memory statistics are measured in KB:
Buffers Cached FreeRatio
-/+ Buffers/Cache: 203000
The cached memory utilisation is around 24%
which is relatively high.
Cached memory is a mechanism used by Linux to speed up file read
and write speed. It cannot be disabled and it would be automatically reclaimed
by the system before memory thresholds are triggered. Recycled memory would be
what no one is using and what is in use will not be released and will not
affect other services.
If the memory utilisation don’t keep increasing, please don’t
worry about it.
