KRaft Performance Improvements

Do we have any performance test results showing the difference between
KRaft vs Zookeeper?

The one that I found online is from Redpanda comparing the tail latencies
https://redpanda.com/blog/kafka-kraft-vs-redpanda-performance-2023#the-test:-redpanda-23.1-vs.-kafka-3.4.0-with-kraft

Can I assume this is a valid comparison?

Also I heard that KRaft will be helpful for the number of partitions on a
cluster. Do we have any test showing the difference?

Are there any expected performance improvements?

Thanks
