Really? Tell that to Mr. Mempool and Mrs. Unconfirmed transactions, https://blockchain.info/charts/mempool-size, https://blockchain.info/charts/mempool-count.

We need Segwit for transactions to be confirmed faster and remain cheap at the same time, plus it also might maintain the no. of unconfirmed transaction below 10,000.

Does anyone know how many transactions would fit in a full block under Segwit?
