Meaning of available, free and buffered memory
: New version (at least 19.07.x) now use total available, used, buffered and cached in LuCi status overview
Issue: What is the difference of total available memory, free and buffered shown in LuCi status overview (or free on the command line)?
Solution:
- Total = free + buffered
- Buffered = memory that is temporarily in use to handle I/O operations
- Free = really free memory
