I'm also having problems like this with large files.  I haven't been able to 
narrow it down but I'll try what you say about org-startup-folded.

Do you also have a problem where sometimes TAB or SHIFT-TAB on a heading has no 
effect?  Some Org files seem to get broken after editing them for a while, and 
some folding no longer works (that is, some headings stay closed, while others 
can be cycled), and the only way to fix it is to reload.

I'll turn on debugging and see what that says.
