are explained in the go docs: https://golang.org/pkg/runtime/#MemStats

The most interesting values for most people are:
|
|
|
|
* HeapAlloc: This is the amount of memory rclone is actually using
|
|
* HeapSys: This is the amount of memory rclone has obtained from the OS
|
|
* Sys: this is the total amount of memory requested from the OS
|
|
* It is virtual memory so may include unused memory
