Using gcc compiler flag in Xcode
<p>Shark has identified a area of code to be improved - Unaligned loop start
and recommends adding -falign-loops=16 (gcc compiler flag). I've added this to 
Other C flags in iphone Xcode both to the dependant project and top level project. However it still does not seem to affect the performance and Shark is still reporting the same problem
so it appears it didn't work.</p>

<p>Am i doing this correctly?</p>
