copy to replicate journal/page/large message file
URL: https://github.com/apache/activemq-artemis/pull/2666#issuecomment-492539004
@franz1981 @clebertsuconic Thanks for the review. I've modified as you
commented. There is no issue in our production env using buffer send:) We just
want to squeeze performance(sometimes tens of GB files needs to be transferred
although it's only happening during catchup). Also in a few months, we'll use
10-gigabit cards for our cluster which maybe make cathup more fast by using
sendfile. We deployed the test and saw that the change saved a visible amount
of CPU.
Flamegraph of master:
Flamegraph of the PR:
As we can see, at least 29% of the total time(21% FileChannelImpl::read and
8% PacketImpl::encode) is saved.
