I'm a software developer so I get that a large DB can slow down a search, but surely caching can speed up the general loading of the app? And there's absolutely no reason for it to take 30 seconds or more just to open a new note window - that's unusable in my book. I adore evernote but it's getting more and more frustrating to use.
This is a major problem for me too. The desktop app takes a long time to open, and even to add a new note is frustratingly slow. I find the new web clipper to be really slow too - all in all it's becoming much less useful for actually taking notes quickly. I'm on a macbook air 11 inch, with about 4K notes.
