SetStyle Method Performance Analysis test

This performance test is to test the time required for code to execute SetStyle methods by changing the background image of a container vbox.

Using the SetStyle method, test the time required for code execution:

SetStyle Method Execution times	Test time (in milliseconds) for the first time	Test time required for second time (MS)	Test time required for the third time (MS)
1	0	0	0
10	0	16	0
1000	250	203	219
10000	2282	2203	2313

After you replace the SetStyle method with the StyleName property, test the time it takes to execute the code:

Milliseconds

StyleName Property Execution times	Test time (in milliseconds) for the first time	Test time required for second time (MS)	Test time required for the third time (MS)
1	0	0	0
10	0	0	0
1000	16	0	0
10000	16	15	10

The SetStyle method consumes performance when the number of executions increases.
The SetStyle method can be substituted with the StyleName property of the object, stylename referencing the CSS style name.
