We have noticed in our performance tests that with bigger buffer sizes > we saw upto ~3x performance boost. Hence, making the copy buffer size a > configurable setting via the new parameter <copybuffersize>. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
