Boost 1.81 will have boost::unordered_flat_map...

• unordered

  10 52 9.4 C++

  Boost.org unordered module

  

We do have other benchmarks where we test the default hash function for strings, which differs between Boost and Abseil. (We also test strings using the same hash function, FNV-1a, for a more level playing field.)

• boost_unordered_benchmarks

  5 14 1.3

• InfluxDB

  www.influxdata.com sponsored

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• parallel-hashmap

  31 2,307 7.6 C++

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

I do this as well in my phmap and gtl implementations. It makes the tables look worse in benchmarks like the above, but prevents really bad surprises occasionally.

• gtl

  5 87 7.1 C++

  Greg's Template Library of useful classes.
