GraphQL - Accelerated
summary
Engineers make GraphQL run much faster on Node.js by applying three concrete steps: cache parsed/validated ASTs so parsing and validation skip repeated work, treat stable queries like prepared statements using variables, and JIT-compile hot queries into plain JavaScript so V8 optimizes them. Performance is measured with clinic flame and load-tested with autocannon, yielding about 20–30% faster typical throughput and up to 2x on complex hot queries.

- 11:34On each and every request the server first has to parse the query to produce an Abstract Syntax Tree and then walk that to execute the query
- 14:37Uses an LRU to cache stable queries
