Which columns define the primary index? Do you have any information if L,M,N is skewed?

For an insert/select you need only one session. More than one session will produce a better performance by Bteq imports and exports.

If it is you (your user) only running this query, you might look for hot amps by

Select Max(currentspool),avg(currentspool),min(currentspool)
from dbc.allspace
where databasename = username
;

If the differences are to big this will be an indication for skewing for the data (L,M,N).
