XlsIO Getting cell.DisplayText takes a lot of time.

Hello!

I use Syncfusion.XlsIO in such scenario:

1. Read template .xlsx file. The file contains first sheet with TemplateMarkers to fill row data and second sheet with formulas to perform calculations.
2. Enable formula calculations by call ws.EnableSheetCalculations();

3. Fill data to ITemplateMarkersProcessor

At this moment I suppose all formulas in the second sheet are calculated.

After that I need to take calculated values from sheet with formulas. I iterate over worksheet.Cells and try to take cell.DisplayText

Unfortunately, I found that cell.DisplayText takes more 90% of time. You can see this in attached trace screenshot.

As I understood from trace analysis the reason of this behaviour is that during getting cell.DisplayText Syncfusion.XlsIO starts formulas recalculation. But I suppose formulas already calculated.
