Why not ask the developers of those mode-lines to take a look and find out why they make pixel-scroll-mode so slow, as opposed to the default mode-line? In any case, the profiles shown in these reports doesn't seem to point to any problems with core facilities related to mode-line, so I'm uncertain how to proceed with investigating this. Would it be possible for you or someone else to come up with a recipe starting from "emacs -Q" and loading as few 3rd-party packages as possible, ideally none at all?
