 This is because WASM architectures at the time of writing this still don't handle parallelism properly.

+A way to import this library into the project that works this arround (in case you might compile to `wasm`-targets) could be as follows:

 ## Benchmarks
 
 Benchmarking is supported through the use of Rust's built-in test framework. Benchmarks can be run without assembly optimizations:
