wy96f commented 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-535831615 > tbh I'm not sure it makes sense to have to have such small timeout in that case, given that depends by disk speed/network bandwidth and total transferred size.... Do you mean initial-replication-sync-timeout? If so, it's ok with default(30000) in master and file region=true, but not in file region=false, so i set it to 3000000 for profiling. > Just one advice: try collecting samples with -t..I wasn't expecting blockUntiWritable to be that costy.... `./profiler.sh -d 60 -t -f xx.svg pid` like this, profiling for master,file region=false/true? For file region=false, should i collect samples from beginning or after 40s(after log showed last page sent)?
