Description

A big drive was made in 2.0 to avoid iterators on the critical path to reduce garbage collection.

 

When task hooks are used, an iterator is used for each info object to pass it to all hooks.

 

As this is on the critical path when task hooks are used, the same reasoning should apply and the iterators be replaced with for loops.
