Yast2 Sequencer performance

I have generated a simple set of forms using the Wizards module and coded it up by hand calling Wizard::SetContents and managing all the events in a single event loop. I modified the code to use the Sequencer module to utilize the ability to modularize the code and manage the wizard sequence better; however, it seemed to have a large performance reduction with the same forms. The Sequencer is nice for managing the workflow for multiple forms but it seems 3-4 times slower. Has anyone seen this? Thanks, dominic.
