Comment (by waddlesplash):

I have investigated this. It seems that there were a couple of areas
 that could be improved and I was able to get some code clean-up done, but
 the majority of the computational time taken is in the re-layout of the
 views of the "prominent" and "all" package lists.

 I wonder why switching to a tab view made this so much slower vs. the card
 view, then. I guess the tab view invalidates the child's layout on each
 tab switch; can we avoid that? That will help restore performance.
