    hashbrown uses aHash by default, which is much faster than std’s SipHash-1-3

    I suppose it’s because the article you’re citing is from april 22nd, and that hashbrown has replaced old std hashmap in this commit, which hash been created on 24th.

    I suppose (can’t test myself) that if you do the test now (hashbrown against std), the performance difference would be negligeable beacuse you would be testing roughly the same algorithms.
