cjkas a8bb377957 fix: track the JSON length instead of recounting it ... Every append found the end of the buffer with strlen(), up to four times per append and four appends per field, so building a response cost the square of its size. /discovery fills a 4 KB buffer and spent about 195 ms of its ~210 ms there (shades 126 ms, groups 69 ms), all on the async_tcp task that serves every socket and web request. Keep the length in the formatter and write every append at the end through one helper. The web response and socket event subclasses and ControllerChunker use the tracked length too. Output is unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>		2026-10-12 16:04:13 +02:00
