> OMID has a LOW_CPU and a HIGH_THROUGHPUT wait strategy (using a disruptor). HIGH_THROUGHPUT does busy waiting, and I'd argue even in production is not the way to run it unless you have a dedicated machine/vm for the TSO.
> For tests it's quite bad, as the disruptor will keep a few cores 100% busy!
