Meaning of available, free and buffered memory

Issue: What is the difference of total available memory, free and buffered shown in LuCi status overview (or free on the command line)?


  • Total = free + buffered
  • Buffered = memory that is temporarily in use to handle I/O operations
  • Free = really free memory
