Highest Performance C++ Libraries to Replace Std Features?

• parallel-hashmap

  31 2,316 7.8 C++

  A family of header-only, very fast and memory-friendly hashmap and btree containers.

actually, std::map and std::set are very inefficient, and can be very advantageously replaces by phmap::btree_map and phmap::btree_set from my https://github.com/greg7mdp/parallel-hashmap repo. Same for unordered_map and unordered_set.

• libunifex

  22 1,355 7.8 C++

  Unified Executors

  

I have no benchmarking experience in multithreading support, but if you want to get something bleeding edge, you could try https://github.com/facebookexperimental/libunifex.

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• tracy

  57 7,814 9.6 C++

  Frame profiler

I would recommend tracy for a low overhead profiler... https://github.com/wolfpld/tracy

• robin-hood-hashing

  23 1,465 0.0 C++

  Discontinued Fast & memory efficient hashtable based on robin hood hashing for C++11/14/17/20

That being said - for unordered containers use https://github.com/martinus/robin-hood-hashing as benchmark.

• corrade

  1 471 9.3 C++

  C++11 multiplatform utility library

For general lightweight containers I would use (https://github.com/mosra/corrade/tree/master/src/Corrade/Containers) see also https://doc.magnum.graphics/corrade/namespaceCorrade_1_1Containers.html .

• llfio

  25 768 6.3 C++

  P1031 low level file i/o and filesystem library for the C++ standard

For high performance local IO definitely use https://github.com/ned14/llfio .
