Setting the Architecture - does it improve performance?

[VIC201]

Setting the Architecture

An iPhone OS device uses one of a set of architectures, which include arm v6 and armv7. The Architectures build setting identifies the architectures for which your application is built. You have two options for specifying the value of this setting:

■ Standard. Produces an application binary with a common architecture, compatible with all supported
iPhone OS devices. This option generates the smallest application, but it may not be optimized to run
at the best possible speed for all devices.

■ Optimized. Produces an application binary optimized for each supported iPhone OS device. However,
the build time is longer than when using the Standard option, and the application is also larger because
multiple instruction sets are bundled into it.

Choose the value for the Architecture build setting in the Build pane of the Target or Project Info window.
If you need to build your application so that it contains executable code for adifferent set of architectures
than these predefined values offer, you can choose Other from the Architecture build-setting value list and
enter the desired iPhone OS–device architecture names.

Has someone tested this with different devices?

For Unity I’m pretty sure the effect goes towards 0 as you don’t compile anything performance related within XCode at all, all comes in precompiled from unity.
