Yes :-) You can see why it's slow by following the logic in pure Python in lib_pypy/_ctypes/, maybe by using just pdb. It's because every character is individually converted to a ctypes object and back before being stored into the string buffer. I guess we could add a special case to massively speed up the common "array-of-char.value = string".
