+## Performance
+
+By default, zio-kafka programs process partitions in parallel. The default java-kafka client does not provide parallel
+processing. Of course, there is some overhead in buffering records and distributing them to the fibers that need them.
+On 2024-11-23, we estimated that zio-kafka consumes faster than the java-kafka client when processing takes more than
+~1.2ms per 1000 records. The precise time depends on many factors. Please
+see [this article](https://day-to-day-stuff.blogspot.com/2024/12/zio-kafka-faster-than-java-kafka.html) for more
+details.
+
+If you do not care for the convenient ZStream based API that zio-kafka brings, and latency is of absolute importance,
+using the java based Kafka client directly is still the better choice.
