Benchmarks are available here, and the Clojure benchmarks make use of transients wherever possible: https://github.com/lacuna/bifurcan/blob/master/doc/benchmarks.md.
More generally, while transients are often used in practice to quickly construct a read-only data structure, the more formal definition is that they provide an O(1) mechanism for transforming between immutable and mutable forms. This isn't possible with purely mutable data structures like Java's HashMap or Bifurcan's LinearMap. So while wrapping these data structures in the Clojure API would provide better performance for construction and lookups, it wouldn't be quite the same thing as a transient.
