Tilman Hausherr commented on PDFBOX-5049:
-----------------------------------------
I'm not persuaded by this because it exposes our cache and adds another table.
Also, the core of problem is the algorithm used in the method, that the
shrinking string width is calculated so often. So that should be fixed either
by knowing / limiting how much there is to warp, or by enhancing this algorithm.
> PlainText.Paragraph.getLines extremely slow on long lines

> The three attached files are very slow when constructing the appearance on
> the field "gendate" (on the last page). That is a multiline field but with an
> extremely long text.
> It happens at "// single word does not fit into width".
