I've spent a while profiling (and the longest time was working out how
to profile the C level of a python shared library module!).

It is slow because of pyuca - the unicode sorting system, combined
with the length of the memos. I sort on the entire memo...

I've added a ~/.jppyrc option to disable this:

[core]
unicode-collation = no

and now it is much faster. The GUI is still slow to manipulate long
memo's though. You can fetch r151 to try this.

I guess it's back to the drawing board with respect to the unicode
sorting! I could have it sort on just the first 15 or so bytes,
maybe. That's in r152; and seems a good compromise.

For memos:

In [1]:import jppy
In [2]:first_memo = jppy.memoList().records()[0]
In [3]:first_ten_bytes = first_memo['text'][0:10]
In [4]:first_memo.category
Out[4]:6
In [6]:jppy.memoList().getCategories()[6]
Out[6]:u'DATEBK3'

etc. If you have a particular 'job' you'd like, let me know and I'll
write an example for the examples directory.
