Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Google made faster Siphash variants, and also HighwayHash that's much faster.

Meow Hash
umash (https://github.com/backtrace-labs/umash) has a similar structure PH block structure, but was designed for decent bit mixing (enough to satisfy smhasher, unlike CLHASH, which needs an additional finalizer) with a lower fixed time cost: 22 cycles for a one-byte hash.
I'm not sure how one would use that linear regression. What kind of hardware offers 675 GB/s of memory bandwidth? 140 bytes/cycle is easily more than twice the L2 read bandwidth offered by any COTS chip I'm aware of. There are also warm up effects past the fixed cost of setup and finalizers that slow down hashing for short input. For what range of input sizes (and hot/cold cache state) would you say the regression is a useful model?
What are some alternatives?
BLAKE3 - the official Rust and C implementations of the BLAKE3 cryptographic hash function
meow_hash - Official version of the Meow hash, an extremely fast level 1 hash
xxHash - Extremely fast non-cryptographic hash algorithm
