Are any other @thunderbird users seeing the issues that @winterschon wrote about in this post? I've been seeing the high resource usage, just not quite as high (but almost as high). This is one of the reasons that I'm moving back to Emacs for my email or looking for a client that is a bit "lighter" on the resource usage.

Thanks!

That is with 5 IMAP accounts, 1 CardDAV, 1 CalDAV and several (manually refreshing) RSS feeds.
