Change the `Op` bench to more closely match the `Xt` bench and add `Loc` benchmark #159

Closed polytypic closed 9 months ago

This PR changes the Op benchmark to more closely match the Xt benchmark. The Op benchmark has been quite useful as it mostly measures the cost of the internal k-CAS algorithm. However, the way the benchmark prebuilds the CAS list makes it unrealistically fast when compared to the Xt benchmark.

This PR also adds a Loc benchmark that currently tests the performance of Loc.incr on a single domain.
