The mempool is where all the valid transactions wait to be confirmed by the Bitcoin network. A high mempool size indicates more network traffic which will result in longer average confirmation time and higher priority fees.

The mempool size is a good metric to estimate how long the congestion will last whereas the Mempool Transaction Count chart tells us how many transactions are causing the congestion.
