>          Key: DERBY-212
>          URL: http://issues.apache.org/jira/browse/DERBY-212
>      Project: Derby
>         Type: Improvement
>   Components: Network Server
>     Versions:
>     Reporter: Kathey Marsden
>     Assignee: Knut Anders Hatlen
>     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.
