hey
Coder,
Hahahaha...no im not certain as im not testing your system under test! but i have seen this behaviour before (when retrieved recordset is too large for my soapui instance to handle) and considering you said you had no problem retrieving records in the hundreds but failed when retrieving tens of thousands its at least a good place to start.....
For a cursory check before you mess around with the vmoptions file, why not monitor soapui's performance in windows task manager to see how much of your laptops resource is being used?
Its still worthwhile making the changes to the vmoptions file to optimise soapuis memory management based on your setup as this wont detract from performance at all if you do it right.
