did you try cPickle instead of pickle?
(also make sure that you're using binary pickles).
if you only use simple data types, the marshal module can sometimes
be faster than cPickle (it's always faster than pickle)

15-20 bytes is more than enough; e.g.
"*"*1000*1000*600
as for exec'ing huge files, it's not that unlikely that the Python compiler
may need 30 bytes per source byte to hold parser trees and byte code
structures. to get exact figures, check the peak memory consumption
when you parse smaller (i.e. megabyte-sized) parts of your file.
