Performance and benchmarks

We don't include benchmarks against databases (for example MySQL, PostgreSQL, SQLite or CockroachDB).The performance differs a lot between deployments due to request latency or database configuration which makes these benchmarks difficult to generalize. Also individual tweaks can improve performance by a lot and produce a potentially deceiving benchmark. For that reason benchmark results for these database adapters are not included.

Ory Hydra

Benchmark results for different endpoints of Ory Hydra. All benchmarks are executed using rakyll/hey. Please note that these benchmarks run against the in-memory storage adapter of Ory Hydra. These benchmarks represent what performance you would get with a zero-overhead database implementation.

All benchmarks run 10.000 requests in total, with 100 concurrent requests. All benchmarks run on Circle-CI with a "2 CPU cores and 4GB RAM" configuration.

BCrypt

Ory Hydra uses BCrypt to obfuscate secrets of OAuth 2.0 Clients. When using flows such as the OAuth 2.0 Client Credentials Grant, Ory Hydra validates the client credentials using BCrypt which causes (by design) CPU load. CPU load and performance depend on the BCrypt cost which can be set using the environment variable BCRYPT_COST. For these benchmarks, we've set BCRYPT_COST=8.

OAuth 2.0 client management

Creating OAuth 2.0 clients

This endpoint uses BCrypt and generates IDs and secrets by reading from which negatively impacts performance. Performance will be better if IDs and secrets are set in the request as opposed to generated by Ory Hydra.

This test is disabled due to issues with /dev/urandom being inaccessible in the CI.
