I am afraid that with thousands of paragraphs, it will still be slow determining the height for given with (e.g. RichTextCtrl needs to do that in Layout anyway). Note that if you load some really big text in MS Word or OpenOffice writer, it can be slow as well before he reformats everything. In you current example, you need to typeset about 4 millions glyphs... Smile

It is strange it is slow on your machine though. What exactly is slow, scrolling?
