Here is an example which generated bech32 addresses:
~snip~
It took
82 seconds to generate those 1 million addresses. This is a rate about
12,195 addresses/sec which is way too slow.

I was curious to try out a Rust implementation and took the first thing I could find on the web when looking for 'Rust Bitcoin address generator'.
So far, very disappointing. I added a loop of 1000 iterations to this, and some disk I/O instead of the print statements:
https://github.com/mrgian/bitcoin-address-generatorIt takes around 5s for 1000 addresses, 538.78s for 100k addresses. Sure, single-threaded, but your initial Python implementation was single-threaded too and just took 82s for 1 million addresses.
As ETFbitcoin mentioned, those Python libraries you use are probably heavily optimized already.
