Are you sure PHP is the bottleneck? The author writes that Clickhouse takes 0.1s for an example request: https://news.ycombinator.com/item?id=42666703 https://news.ycombinator.com/item?id=42666703 PHP would need to be adding 0.1s CPU time for processing the request for the PHP code to become the bottleneck. That seems unlikely.
