I have changed the non cryptographic hash used by Caddy from fnv1 to xxhash, which is known to have better throughput than the FNV family of hashes (https://github.com/Cyan4973/xxHash). Was wondering if there is any comments on creating a PR for this change to the main caddy branch? Just a suggestion, looking to find ways to contribute to the caddy project. Love y'all's work. :-)
