Thanks for the report, and once again our apologies that we don't have
good test setups for large data sets.

I think jk reported a slow migration as well but I think it might have
been a different one? We should fix both for stable/2.2.

Stephen, did we squash all of these for 3.0 or should we fix them on
master also?

Kind regards,
