Its not the SNDDST eating up the time, it's the actual RPG - Java call
that seems to be slowing it down. I intend to get rid of QDLS as well,
its just not as high a priority.

Sharon,

You might try getting rid of the use of SNDDST and using a file system
besides QDLS.

The performance of QDLS is very, very poor.

You can look in the archives for alternatives.

I have a question. I recently used Scott Klement's Excel articles to
create an Excel processor. It uses a control file that describes
what
file, what Excel worksheet to use as a base, then adds the data to a
new
copy of the worksheet. Once this is done, another job actually sends
the file from the IFS to the user. I had to separate the creation and
the sending since SNDDST only uses QDLS and QDLS cannot be used in a
job
where Java is involved (multi-threading).



The process itself works great. It runs every 10 minutes looking for
new requests to process. Now we have discovered that some of these
requests are huge files. Over 75K rows to be created. This one
request
ran for over 45 minutes on a usually lightning box.



This lpar has over 8 gig memory and its on a M525-7792 so its usually
a
speed demon.



I really need to decrease the time significantly. Any ideas? Is
there
another way to do this, perhaps without Java?
