Brandon Li updated HADOOP-9669: ------------------------------- Summary: Reduce the number of byte array creations and copies in XDR data manipulation (was: There are multiple array creations and array copies for a single nfs rpc reply) > Reduce the number of byte array creations and copies in XDR data manipulation > ----------------------------------------------------------------------------- > > Key: HADOOP-9669 > URL: https://issues.apache.org/jira/browse/HADOOP-9669 > Project: Hadoop Common > Issue Type: Improvement > Components: nfs > Reporter: Tsz Wo (Nicholas), SZE > Assignee: Haohui Mai > Attachments: HADOOP-9669.001.patch, HADOOP-9669.002.patch, > HADOOP-9669.patch > > > XDR.writeXxx(..) methods ultimately use the static XDR.append(..) for writing > each data type. The static append creates a new array and copy data. > Therefore, for a singe reply such as RpcAcceptedReply.voidReply(..), there > are multiple array creations and array copies. For example, there are at > least 6 array creations and array copies for RpcAcceptedReply.voidReply(..). -- This message is automatically generated by JIRA.
