Timothy Bish created PROTON-1808: ------------------------------------ Summary: [proton-j] FrameWriter allocates additional buffer capacity inefficiently Key: PROTON-1808 URL: https://issues.apache.org/jira/browse/PROTON-1808 Project: Qpid Proton Issue Type: Improvement Components: proton-j Affects Versions: proton-j-0.26.0 Reporter: Timothy Bish Assignee: Timothy Bish Fix For: proton-j-0.27.0
When writing a Transfer that has a larger payload than previously seen the FrameWriter may need to grow its internal buffer to accommodate that transfer. The current strategy is to double the capacity of the current buffer and copy the old bytes into the new buffer and then check again if there is room. Depending on the frame size setting and the size of the transfer this can result in a large amount of garbage being created and a number of unneeded copies of encoded performative data. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
