franz1981 edited a comment on issue #2845: ARTEMIS-2336 Use zero copy to replicate journal/page/large message file (AGAIN) URL: https://github.com/apache/activemq-artemis/pull/2845#issuecomment-535443555 @wy96f Good analysis :) Yep, so the possible solution I see is to tune differently `lowWaterMark` and `highWaterMark` > 1 MB to allow chunk writer queue to be drained faster and make the flow control more accurate (effectively backpressured by the TCP buffer, instead of being limited by the netty *before* it)
