You're going to need to instrument to find out what is happening
(either at the database level or the MasonX::Profiler level).  3.8.7
contained a number of rewrites to make that code streamy rather than
generating the entire file before letting it be downloaded.  Although,
with 3.8.7 you almost certainly have the bug where the column headers
won't sort properly, so you may want to think about upgrading to fix
that.
