Apple to Apple Comparison: M1 Max vs. Intel
Its configured with the fastest memory possible on the Threadripper. The exact specs and RAM stick models match the ones mentioned in the preceding article, I have linked below. We didnt include those, as we don’t know the exact specs of RAM modules in MacBooks.

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).
