Dear my friend....
I scarifies it only for DIU forum member.
At first right click on MY computer..Then click on Properties
After click on advance and then settings.. follow the arrow..
Then, Click on "Advance", next click on "Change"
After, here you can find, Initial size and maximum size
You can see here my initial size is 2976 and Maximum size is 5952.
Now i just here increase the the initial size is 5952 and maximum size is 11904 .
Just double the number. in mathematics equation, 2976 X 2 = 5952 and Maxumum value is 5952X 2 = 11904
see the next pic
now click on "Set" Then "Ok" and Finally click "ok". and run your program..You must get double speed.
Suppose your initial size is 322 and max is 644. then you write on initial size 644 and maximum value is 1288.
