Couldn't we avoid this copy-paste by wrapping by Bufferred streams where needed? > Use buffered file output stream for MimeMessageInputStreamSource > ---------------------------------------------------------------- > > Key: JAMES-2343 > URL: https://issues.apache.org/jira/browse/JAMES-2343 > Project: James Server > Issue Type: Improvement > Components: James Core > Reporter: TzeKai Lee > Priority: Major > > Currently MimeMessageInputStreamSource use DeferredFileOutputStream from > commons-io which does _not_ buffer output stream when switched to > FileOutputStream. In my preliminary test, simply wrap FileOutputStream with > BufferedOutputStream could make a 50% performance improvement for mail larger > than deferring threshold (currently 100kb). -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: server-dev-unsubscr...@james.apache.org For additional commands, e-mail: server-dev-h...@james.apache.org
