Simplifies task execution. A single slow task that requires a lot of bloom checks may slow down all other tasks executed within the same multiplexed execution.
While the idea of multiplexing requests/tasks was to reduce file i/o as well as memory consumption, it turned out that the downside of slowing down individual requests does not benefits.
More observations and metrics are needed to verify this assumption, but initial tests showed a significant decrease in p99 latency for bloom gateway requests.
