slow to retrieve email after update

lg g3 - since a recent update it's taking up to 20 seconds to retrieve and delete emails picked up via data or wifi.. used smart cleaning but no improvement..

Welcome to Android Central! I assume this is with the stock Email app. Have you tried removing the email accounts, then adding them back again?
