Updating map_benchmarks: Send your hashmaps!
Also, I'm testing https://github.com/greg7mdp/sparsepp which is based on google's sparsehash

Who here is ready to see some 64MB blocks on mainnet?
Hey thanks for the mention /u/jtoomim. I see that you used sparsepp in CoinsViewCache. A phmap::flat_hash_map would probably be similar for memory usage, but likely faster (because of parallel lookup with SSE instructions and contiguous memory storage in one array).

Introducing B++ Trees, a C++ B+ Tree library
Apart from persistent mode (which is very cool!), what are design differences with abseil btree and tlx-btree (former stx-btree)?
What are some alternatives?
