We are using powerbuilder with Sybase SQL Anywhere 5.5.  An issue we are 
having is that datawindows that have records 10000+ slow down almost 
exponentially during a retrieve the higher amount of records there is.  A 
40000 record datawindow should not take 5-10 minutes to retrieve on a 1ghz 
machine.  Have any of you experienced a similar problem?  Please let me 
know any suggestions you have.  Please email me at johnowens50@hotmail.com

Two possibilities:

1) your computer is memory-starved.  Is the paging rate going up as the
retrieval progresses?
2) you have some group calculatations that are being recalculated as each
row is retrieved.

Have you coded anything in the retrieverow event?

No there is nothing in the retrieve row event.  There is just a massive 
amount of data to be displayed and it seems that during the retrieve, the 
system retrieves slower as the number of rows get larger.  The redraw 
command "IS" turned off during this process.

Do you have Retrieve Rows to Disk set?
It may also help to defrag your disk.
