My Thunderbird connects to Google Apps with an IMAP account setup. It is a frustratingly slow user experience. Typing lags, folders and emails slow to display etc. I am guessing that my NOD32 ver 4 Antivirus setup may be slowing things .. what settings are safe to disable in NOD32 that might speed things up? eg untick scanning of receive, sent, read mail? setting Thunderbird as an excluded app from protocol filtering? exclude Thunderbird profile folder from real time scanning?
