It's probably not a problem with your Perl installation. I'd wager that what's going on is that you're pulling all of the data into a big Perl data structure, like an array of array references. That would be the case if you're using fetchall_arrayref to get your data. But this cannot be determined unless you post your code.

Going with my guess: the problem is probably that Perl takes relatively more memory to store a given amount of data than SQL*Plus, but that's in the nature of the Perl beast => throw memory at a problem to increase efficiency.

A possble solution is to change your code to work with fetchrow_arrayref (note: "row", not "all") which gets the data from the result set one row at a time, instead of snarfing the whole thing into memory at once. That may reduce the program's memory needs. It might slow down your program's execution -- but having it finish in 10 minutes is faster than never, I suppose =)
