If we handle the total request on the Reader thread, we go faster. Lets take it up over in HBASE-14479. > Metric for active ipc Readers and make default fraction of cpu count > -------------------------------------------------------------------- > > Key: HBASE-15967 > URL: https://issues.apache.org/jira/browse/HBASE-15967 > Project: HBase > Issue Type: Sub-task > Reporter: stack > Assignee: stack > Attachments: HBASE-15967.master.001.patch > > > Our ipc Readers are hard coded at 10 regardless since . Running w/ less Readers, we go faster..(e.g. 12 Readers has us doing 135k with workloadc and 6 readers has us doing 145k).. .but hard to tell what count of Readers are needed since no metric. > This issue changes Readers to be 1/4 the installed CPUs or 8, whichever is the minimum, and then adds a new hbase.regionserver.ipc.runningReaders metric so you have a chance seeing whats needed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
