Subject [jira] Created: (DERBY-212) Optimize some specific methods in Network Server to improve performance
Date Mon, 11 Apr 2005 01:44:17 GMT
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: 10.1.0.0    
    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.
