Knut Anders Hatlen commented on DERBY-212: ------------------------------------------ The method buildDB2CursorName() mentioned in the description of this issue seems to have disappeared from the code. A comment in DRDAConnThread.parsePKGNAMCSN() says // Note: This string is parsed by DRDAStatement.buildDB2CursorName() but there is no such method in DRDAStatement. There is however a method called extractPkgcnstknStr() which parses the string returned by parsePKGNAMCSN() and seems to take a lot of resources. > Optimize some specific methods in Network Server to improve performance > ----------------------------------------------------------------------- > > Key: DERBY-212 > URL: http://issues.apache.org/jira/browse/DERBY-212 > Project: Derby > Type: Improvement > Components: Network Server > Versions: 10.1.1.0 > Reporter: Kathey Marsden > Priority: Minor > > In reviewing the Network Server Code and profiling there were > several areas that showed potential for providing performance > improvement. > Functions that need optimizing to prevent unneeded object > creation and excessive decoding > parsePKGNAMCSN() > parseSQLDTA_work() > buildDB2CursorName() > In DDMWriter and DDMReader, use System Routines in > java.util.Arrays and System.arrayCopy instead of > writing code to do functions like copy arrays and > pad strings. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
