Quick Tip to Improve Performance: Use FlexSheet's deferUpdate Method

Many operations in FlexSheet—such as adding a new sheet, setting cell data, etc.—will refresh the FlexSheet. Multiple operations lead to multiple refreshes, which will eventually lead to a slower performance.

As the FlexSheet will be refreshed only once, the performance of the FlexSheet will be improved.
