Have you found a solution?  I have to paginate over 2.5m rows, and am
having the same issue.

The root of the issue is the SQL query runs a LIMIT offset, per_page, which
isn't efficient in large tables.  

I'm considering writing in a flag to grab the ids of the rows, then
selecting the rows individually.  However, I'm hoping somebody else has
solved pagination over large data sets.  I can't be the first to run in
this issue.
