Answer:
Instead of memory management, try to take a look at the DB side.
Watch your System's work processes while your background job at SM50 Transaction. If there are some lines containing "Sequential Read - -tablename-" kind of things taking longer times than other,
probably you really need to optimize your select statements against that tables' index.
I must say that, sometimes changing a couple of select statements causes 10-15 times faster running programs.
Answer:
yeah.. check for sql statements.. esp those select * from
