Tom,
> Huh? Doubled compared to what?
Compared to how much data writing I can do to the database when pgsql_tmp
isn't engaged.
In other words, when pgsql_tmp isn't being written, database writing is 9mb/s.
When pgsql_tmp gets engaged, that drops to 4mb/s.
Alternatively, the WAL drive, which is the same hardware, will write at
10mb/s.
