It goes up and the goes back down again... that is quite normal.

how big is your source table? memory use is relative the the source size..

if you table has lots of columns it will slow things down as MG does a
select * from table so all the other columns
which aren't needed are also returned... the Map 20 odd ADMP* columns can
really exacerbate this.

One thing you can try is to generate a simplified version of your table...
no need to use data at a 50mm resolution
for a state map when one pixel is say equivalent to 50m on the ground.

The same data from SDF is rendered much faster than from oracle which makes
the memory use less obvious
