Benchmarks

The following benchmarks provide an overview of the performance that can be expected from Orion. If performance is of great importance, users are encouraged to benchmark Orion on their own systems.

The following benchmarks were run with:

• Rust version: rustc 1.56.0 (09c42c458 2021-10-18)
• Command: cargo bench
• Orion version: 0.16.1
