Parallel prefetcher #424

Closed Scooletz closed 2 weeks ago

Scooletz commented 2 weeks ago

Another, simpler take on the Merkle prefetcher. This PR does it by providing the following:

  1. BitFilter atomic operations
  2. Delegating Prefetch calls to ThreadPool.QueueWorkItem so that no queue is needed
  3. Ensuring that the given prefetch is not called twice.
  4. Making it based on ReaderWriterLockSlim
