Thank you for your prompt response. It is good to know that buff/cache memory will be released as needed due to heavy traffic down the road. Warm rgds;

Buff/cache is free memory put to good use - like cache files. Memory that you’re paying for but sits idle. If you get more traffic the buff/cache memory will be immediately re purposed as needed.
