Why is debugging in eclipse/pydev so slow for my python program?

Question

I have a relatively simple (no classes) python 2.7 program. The first thing the program does is read an sqlite dbase into a dictionary. The database is large, but not huge,

Answer 1

I simply commented this line out:

np.set_printoptions(threshold = 'nan')

It seems eclipse is trying to keep up with too much information.
