Leapfrog 0.2.0 (improved concurrent rust hashmap)
I'm announcing v 0.2.0 of leapfrog (crate), which adds new features and fixes the collision problems of the previous version. The performance is slightly reduced, but not by much and the maps are still very fast.

On my way to make the production rusty
You can try Leapfrog as your concurrent hashmap implementation https://github.com/robclu/leapfrog. I recently stumbled across it and was pleased by its performance

Announcing Leapfrog, a faster concurrent HashMap
For a personal project I needed a concurrent HashMap, so thought I would port one of the fast C++ hashmaps to Rust., which I have called Leapfrog. The API is similar to the HashMap in the std library, but to improve concurrent performance it is slightly different in places.

Leapfrog 0.2.0 (improved concurrent rust hashmap)
The maps now stores both keys and values,. The HashMap (single threaded version) is 1.2-1.5x the std HashMap and the LeapMap is between 1.6 - 2.3x the next fastest concurrent hash map on 30 cores for exchange and read heavy workloads, on these benchmarks. For rapid growth type workloads it is less performant (0.8x the performance of DashMap) but better than the rest. See the crate, repo, and linked benchmarks for more details. The benchmarks, however, definitely need to be extended to cover more use cases as they are quite limited at the moment.
