That was for what I'd imagine is v0.1 quality code, they said there were plenty of optimizations available to make it at least parity with the C client. Secondly, the issue was the system performance between Wallaro and the Kafka client, not necessarily the raw performance of the library.

Yes, that's correct on both counts.

Pony Kafka is almost completely untuned as of right now. We expect there is a lot of low hanging fruit on that front that will give us significant gains.

And yes, we're concerned about the potential thread pool contention between Pony and librdkafka.

Copying data in memory between libraries is slower than actually getting the data across the network from the Kafka cluster itself? Seems like a strange bottleneck if so.
