Hi all, I posted an update on the post ( https://blog.liveramp.com/2013/04/08/kafka-0-8-producer-performance-2/) to test the effect of disabling ack messages from brokers. It appears this only makes a big difference (~2x improvement ) when using synthetic log messages, but only a modest 12% improvement when using real production messages. This is using GZIP compression. The way I interpret this is that just turning acks off is not enough to mimic the 0.7 behavior because GZIP consumes significant CPU time and since the brokers now need to decompress data, there is a hit on throughput even without acks. Does this sound reasonable?
