Sad to hear others are having this issue. I've been an Evernote user for a long time and have over 30k notes. I was thinking that must be the problem but seeing all of your posts clearly that isn't it. Over the last year I have been using Evernote less as it's become such a heavy application and it's too expensive for me to run while I work. I need a feature in it today but the performance is so poor I'll be avoiding it going forward.
