Syncfusion Blazor Code Generator performance Validated

On my first attempt at using the Code Generator, it performed so slowly in just selecting the control to insert that I thought the program was in a logic loop of some sort.  It finally did come up with a dialog.  I chose not to actually insert the control.  Instead I was curious about the delay, whether this was just a case of downloading resources that were needed.  So, it selected a different control.  That also was a big delay.  I then selected the original control again.  I noticed only a small improvement.  After experiencing that, I went no further, determining that the slow response rendered the tool to be of questionable value.  Please reengineer the tool to perform responsively.
