[GitHub] [kafka] Hangleton commented on pull request #13312: KAFKA-14766: Improve performance of VarInt encoding and decoding

   Thanks for the PR. It is interesting that unrolling the loop while keeping the same underlying logic yields this increase in throughput for writing varints. A few questions:
   
   - What CPU architectures have this been tested on? 
   - Do we have any data on how these gains translate in latency reduction with real requests from canonical workloads?
