Performance

Fast resolves for small explicit service graphs.

Injex caches dependency plans and uses a fast path for common constructor-injection graphs: singleton infrastructure plus transient application services.

Benchmark shape

The benchmark repeatedly resolves this graph:

• singleton Settings instance;
• singleton ApiClient(settings);
• transient repository, email sender, and audit log;
• transient RegisterUser(repository, email_sender, audit_log).

Local result

Benchmarks are synthetic and not a universal ranking. They show the approximate overhead of Injex in its target shape: small explicit graphs reused by APIs, workers, CLIs, and tests.
