calibre allows TOC entries to point to locations within HTML files. This is so that you dont have to split up your book into one HTML file per TOC entry if you dont want to. Unfortunately, ADE for some reason, that I'm sure Peter can explain, doesn't handle TOCs with this type of entry very well. For instance, if you view the same epub file with calibre's epub viewer, there is no delay in opening the TOCs. Hopefully, this behavior will eventually be fixed in ADE.

As for chapter changing being slow, as far as I know that time depends only on the complexity of the markup/size in each chapter, which is not under calibre's control.
