Multiple functionality together at a time

If I would like to do number of function at a time without much loading then for that which option is best (for the purpose of less loading, fast execution & crash issues)...

1). NSThread

2). performSelectorInBackground

3). NSOperationQueue

Or any other than the above all? Please suggest me the best & the appropriate solution. Thnaks in advance for all the links & guidance.

Grand Central Dispatch would be the best I think.

// Job 1
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^{

    // Heavy work here...

});

// Job 2
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^{

    // Heavy work here...

});

And if you want to do something on the main thread from within those (eg. updating UI), use:

dispatch_sync(dispatch_get_main_queue(), ^{

    // Update UI...

});
