[pypy-issue] [issue865] Struct.pack and unpack 3x and 6x slower than CPython

[Carl Friedrich Bolz]

Carl Friedrich Bolz <cfbolz at gmx.de> added the comment:

This is mostly a property of the insanely long format strings for pack and
unpack. For human-sized format strings (e.g. struct.pack("iii", 1, 2, 3)) PyPy
is much faster than CPython, both for pack and unpack. Therefore I am closing
the issue.

If somebody is of the opinion that struct format strings are in practice
commonly thousands of characters long, please reopen it.
