> 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.
