AW: Re: DataQueue performance jt400Native 10x slower then RPG

when you look at the source of jt400Native.jar you can see that it also calls the native srvpgm in /QSYS.LIB/QYJSPART.SRVPGM
 so there is only a minimal java layer. there is no chance jdbc could get near this performance.
 
 i hoped someone with deeper knowlege of the performance impacts of calling rpg from java via jni could help.

     Maybe just for having the bigger picture: Have you tried you use a simple
   select from the dataqueue service from jdbc:
   Like:
   Select * from table(qsys2.QSYS2.RECEIVE_DATA_QUEUE()...
   The reason why I suggest that is that Db2 uses ILE under the covers (I
   guess)  to read the queue - and maybe that will give you the extra
   performance ...
   .. I am just guessing .... Just try to get your performance back with
   straight jtOpen and JDBC
