From the README:
- Uses less memory
Apart from utilizing the JIT capabilities of the JVM, this server is substantially faster because it uses a separate registry for “simple” queries. A “simple” query is a query by one predicate, e.g. equality. So for most use cases (subscribe to an object by id or by pointer), it will use the “simple query” registry, which is O(log(n)) vs O(n) for the regular (by class name) query retrieval.
