Epicor Web Access and reports preview time

Epicor Web Access opens reports at it’s own scheduled intervals. In Rich Client there is a way to update the interval time and reduce if required. How would one do this changes on Epicor Web Access?

I have tried to reduce


but it still would take around 30 seconds to popup the .pdf file that is generated.

Any help will be appreciated to speed up the time it takes to popup the .pdf file. On the rich client it opens almost immediately, i.e. < 3. We use Book listing reports under Financial Management/General Ledger/Reports as a benchmark.
