Which kind of profiler are you using? It possible that CPython builtin functions are not profiled the same way as PyPy's.
lsprofcalltree.py .
From APSW's source code, i think that it uses this API:
(in cursor.c) PyUnicode_DecodeUTF8
Maybe lsprofcalltree doesn't profile it?
Indeed. CPU cost is hidden in the cursor method.

I would suggest using valgrind. It's a very good (albeit very slow) tool for seeing C-level performance. I remember seeing it both for CPython and PyPy when trying. Can you try yourself?
