GraphQL performance improvements

• GraphQL’s conventional depth-first execution design can be inefficient.
• Switching to a breadth-first approach can significantly improve performance.

• We found IO wasn’t always the bottleneck frequently it was GraphQL’s conventional depth-first execution design

  — Lars Brownworth

• Executing breadth-first instead resulted in a 15x faster field-level execution.

• Less GC overhead, four-plus seconds off P50 end-to-end time

  — Lars Brownworth

• Understanding the technical aspects of GraphQL execution is crucial for optimizing performance.
• Performance metrics highlight significant improvements with the breadth-first approach.
• The insight provides a specific technical analysis of GraphQL performance.
