How to manage parallely process
My situation is
I have to execute multiple processes
try to run ( 15 to 20 ) process parallely
and more than 20 requests starting making Queue for those request
As any request process gets completed so
take item in Queue to process in it and so on
In my mind i have 2 solution for that
1) wait call back 2) asyn call back
whats the difference between them
Should i prefer any of them or some thing else which is perfect for me
kindly suggest
thanks
