At LiveRamp we are considering replacing Scribe with Kafka, and as a first
step we run some tests to evaluate producer performance. You can find our
preliminary results here:https://blog.liveramp.com/2013/04/08/kafka-0-8-producer-performance-2/
hope this will be useful for some folks, and If anyone has comments or
suggestions about what to do differently to obtain better results your
feedback will be very welcome.
