Andreas Kling dba6216caa LibWeb: Skip CSS tokenizer filtering when string has no '\r' or '\f' ... When loading a canned version of reddit.com, we end up parsing many many shadow tree style sheets of roughly ~170 KiB text each. None of them have '\r' or '\f', yet we spend 2-3 ms for each sheet just looping over and reconstructing the text to see if we need to normalize any newlines. This patch makes the common case faster in two ways: - We use TextCodec::Decoder::to_utf8() instead of process() This way, we do a one-shot fast validation and conversion to UTF-8, instead of using the generic code-point-at-a-time callback API. - We scan for '\r' and '\f' before filtering, and if neither is present, we simply use the unfiltered string. With these changes, we now spend 0 ms in the filtering function for the vast majority of style sheets I've seen so far.		2024-07-20 15:35:30 +02:00
