High used and cached memory

Installing and Using OpenWrt

Hello there!!

I've got a question, is this a normal behaviour of the memory management from the router:

949×265

My concern is that it says 77% is available but at the same time says 94% is used... maybe is the cached memory? and why is so high?

Thanks!

Yes thats normal, the cache will eat-up memory if used and will be freed automatically if system memory is needed/allocated again.

You can flush the cache via this command and if you encounter problems or add it as a scheduled routine command, but you should not need to.

sync | echo 3 > /proc/sys/vm/drop_caches
