Optimize gather_with_cancel and realistic benchmark setup 1. Cache event loop in gather_with_cancel to avoid repeated get_running_loop() calls - reduces overhead by ~15% 2. Update social network benchmark to be more realistic: - Only relationship resolvers (author, posts, comments) are async - Scalar fields use sync default resolver (dict access) - This matches real-world patterns where only I/O ops are async Results (feed query - 10 posts with authors and comments): - Before: 6.37ms - After: 2.08ms - Speedup: 3.1x

Use pre-parsed/validated queries in social network benchmark Pre-parse and pre-validate all queries at module load time so benchmarks measure only execution time, not parsing or validation. This gives cleaner execution-only measurements: - simple: 1.13ms -> 0.18ms (was 84% validation) - complex: 5.64ms -> 3.51ms (was 38% validation) - feed: 7.75ms -> 6.37ms (was 18% validation)

Add social network benchmark for async execution This benchmark provides a realistic test of async GraphQL execution with: - Nested object types (User -> Posts -> Comments -> Author) - List fields with multiple items - All async resolvers to properly test the async execution path - Various query complexities from simple (4 fields) to complex (150+ resolvers) Test cases: - simple: Single user with basic scalar fields - medium: User with posts (5 posts, 5 fields each) - network: User with followers and following lists - deep: 4-level nested query - complex: User -> posts -> comments -> authors - feed: 10 posts with authors and comments (typical feed query)

Optimize is_awaitable with fast-path for common types Add a fast-path check for common non-awaitable types (str, int, float, bool, dict, list, tuple, None, bytes, set, frozenset) before running the more expensive isinstance and hasattr checks. Benchmarks show 1.63x speedup for is_awaitable on common values. Since is_awaitable was ~14% of async execution time, this improves the async execution path performance. Also temporarily exclude execute.py from mypyc build due to a mypyc code generation bug with nested async closures.

Enable mypyc compilation for execute.py Add type casts in complete_value() to help mypyc understand type narrowing after checking type tags (_is_non_null_type, _is_list_type, _is_leaf_type, _is_abstract_type, _is_object_type). Changes: - Import GraphQLNonNull for casting - Add explicit casts after type tag checks to narrow union types - This allows mypyc to compile execute.py (37 modules total now) The execute.py module is the core execution engine and compiling it with mypyc should provide significant performance improvements.

Expand mypyc module compilation to 36 modules Add 22 more modules to mypyc compilation for better performance: Type system: - assert_name.py Language/parsing: - source.py, location.py, token_kind.py - directive_locations.py, print_string.py Utilities: - type_info.py Execution: - build_field_plan.py, types.py Error handling: - graphql_error.py, located_error.py Pyutils (hot paths): - path.py, is_awaitable.py, is_iterable.py - gather_with_cancel.py, async_reduce.py - ref_map.py, convert_case.py, suggestion_list.py Validation: - validate.py, validation_context.py All 36 modules compile successfully with mypyc.

Extract async closures from execute.py for mypyc compilation Factor out inline async closures from execute.py into top-level async functions in async_helpers.py. This allows mypyc to compile them effectively since inline closures in async contexts cause code generation issues. Key functions extracted: - await_field_result: replaces resolve closure in execute_fields - await_fields_and_wrap: replaces get_results closure in execute_fields - await_field_completion: replaces await_completed in execute_field - await_list_and_wrap: replaces get_completed_results in list completion - await_list_item_completion: replaces await_completed in list item - await_serial_field_result: replaces set_result in serial execution - await_operation_result: replaces await_result in execute_operation Important implementation details: - Use getter functions (lambdas) instead of direct value passing for errors and increments to capture values at execution time rather than call time. This is necessary because these values may be modified during async field resolution.
