Ah! Well there's a ton of impacts starting from having less regions :) But definitely compactions will take a lot longer the bigger the regions are since more and more is done in a single process.

Oh sorry, total. 14k on a single RS is impossible/suicide if you have any data in there because it would OOME trying to load the indexes (better in 0.92 tho). J-D
