Some big claims, but I wonder if there are some published repeatable benchmarks

Also when someone claims 1000x better Performance I want to know why. For example MySQL or PostgreSQL -> Clickhouse I can clearly attribute to column store, compression, vectorization, parallel execution on multiple CPU cores and machines...

For what it's worth, there are some benchmarks of kdb+ (the database built on k) here - https://tech.marksblogg.com/billion-nyc-taxi-kdb.html (it's overall a fantastic series of blog posts).
