Here are two new patches. The first one takes into account the Martin
wishes about comments. The second also rejects optimization for ASCII.
On the Intel Atom last patch annihilates acceleration for some cases
(mostly-ascii with UCS2 data):

utf-8 'A'*9999+'\u0100' 124 (+8%) 288 (-53%) 134
utf-8 'A'*9999+'\u8000' 124 (+8%) 291 (-54%) 134
utf-8 '\u0100'+'A'*9999 78 (+5%) 123 (-33%) 82
utf-8 '\u8000'+'A'*9999 78 (+5%) 124 (-34%) 82
On the AMD Athlon there is no noticeable effect. |
