Its not caused by there actually being different size encodings but
that the code is checking encoding size 2-4 times for each character.
Back in 3.2 the comparison loop looked like:
while (len1 > 0 && len2 > 0) {
Py_UNICODE c1, c2;
c1 = *s1++;
c2 = *s2++;
if (c1 != c2)
return (c1 < c2) ? -1 : 1;
len1--; len2--;
}
For 3.3 this has changed to
for (i = 0; i < len1 && i < len2; ++i) {
Py_UCS4 c1, c2;
c1 = PyUnicode_READ(kind1, data1, i);
c2 = PyUnicode_READ(kind2, data2, i);
if (c1 != c2)
return (c1 < c2) ? -1 : 1;
}
with PyUnicode_READ being
#define PyUnicode_READ(kind, data, index) \
((Py_UCS4) \
((kind) == PyUnicode_1BYTE_KIND ? \
((const Py_UCS1 *)(data))[(index)] : \
((kind) == PyUnicode_2BYTE_KIND ? \
((const Py_UCS2 *)(data))[(index)] : \
((const Py_UCS4 *)(data))[(index)] \
) \
))
There are either 1 or 2 kind checks in each call to PyUnicode_READ
and 2 calls to PyUnicode_READ inside the loop. A compiler may decide to
move the kind checks out of the loop and specialize the loop but MSVC
2010 appears to not do so. The assembler (32-bit build) for each
PyUnicode_READ looks like
mov ecx, DWORD PTR _kind1$[ebp]
cmp ecx, 1
jne SHORT $LN17@unicode_co@2
lea ecx, DWORD PTR [ebx+eax]
movzx edx, BYTE PTR [ecx+edx]
jmp SHORT $LN16@unicode_co@2
$LN17@unicode_co@2:
cmp ecx, 2
jne SHORT $LN15@unicode_co@2
movzx edx, WORD PTR [ebx+edi]
jmp SHORT $LN16@unicode_co@2
$LN15@unicode_co@2:
mov edx, DWORD PTR [ebx+esi]
$LN16@unicode_co@2:
The kind1/kind2 variables aren't even going into registers and at
least one test+branch and a jump are executed for every character. Two
tests for 2 and 4 byte kinds. len1 and len2 don't get to go into
registers either.
