Question: Problem with large document block (large expression) in maple

Hello, when I write a large document block in maple and want to do some operations, maple shows wait cursor (hourglass) for 2-3 minutes again and again. I attached a sample file below. 

I found out when maple is installed , javaw.exe also instal and when I open bellow file, the javaw use 15% of cpu and this cause maple works slowly. 

the attached file is just an example for large document block and I undrestand that it can be simplified. I want to know how to handle large expressions generally?
