"Can you re-measure following the recent parser + lexer + bom handling changes?

That said the 0-delay timer did seem low to me when i was doing the bom handling stuff."

Updated the results with the latest webkit baseline r64659. Looks like performance degradations are now much smaller <4% difference. We can probably close this bug.
