ASE 12.5: First retrieve slow

Hi,

We're currently on Sybase ASE 12.5.  When running reports to retrieve data based on customer account id, we find that the first retrieve is slow.  Any subsequent retrieves of the same report, for the same customer, with different date ranges, is significantly faster.  We've added the necessary indexes that the report is using to retrieve the data, but we still notice this slow first retrieve.  Is there any way around this, short of running a retrieve for the account in the background, as soon as we know which account the user wants to run the report for?  Any ideas or thoughts are appreciated.

Thank you,
