Benchmarks

Rendered from docs/benchmarks.md in the repository when the site was built.

benchmarks/Inngest.Benchmarks measures the work the SDK does on every call from Inngest: parsing the request, replaying memoized steps, writing the answer and checking the signature. It uses BenchmarkDotNet and touches no network.

The figures below are indicative. They come from one run on a laptop that was busy with other work, so treat them as orders of magnitude. A full benchmark run on dedicated hardware is coming.

Work	Mean	Allocated
Run the first step of a run	5.1 µs	6.4 KB
Replay 10 memoized steps	14.4 µs	17 KB
Replay 100 memoized steps	107 µs	118 KB
Parse a call that carries 100 step results	33.3 µs	27.6 KB
Verify the signature of a 1 KB request	1.18 µs	320 B
Write the sync body of 20 functions	22.5 µs	16.3 KB
Send one event through the client	1.49 µs	3.8 KB

Each memoized step adds about 1.1 µs and 1.1 KB on top of about 4.5 µs and 6 KB per call. A middleware that overrides nothing adds 8 to 9% to a call.

Running them

dotnet run -c Release --project benchmarks/Inngest.Benchmarks -- --filter '*' --job short

--job short runs the 22 cases in about two minutes; leave it out for BenchmarkDotNet’s slower, more precise default job. Run them in Release on an idle machine and compare results only with runs from the same machine.

The figures above used the default job on 2026-10-29: an Apple M3 Max, .NET 10.0.12, BenchmarkDotNet 0.15.8, with a load average that fell from 29.6 to 3.2 during the run. The full reports are in docs/results/benchmarks.
