Is this memory usage normal?
Hi
This behavior is normal.
OpenWrt uses BusyBox’s Top utility, and the memory usage shown reflect %VSZ rather than true memory consumption.
This includes uninitialized memory and memory shared across processes, so the numbers often appear higher than the actual usage.
As long as the available memory shown in Status > Overview looks normal, there is no cause for concern.
If you need a more accurate view of real memory usage, we recommend using htop or free.
