Debug Gauges

New debug gauges in Xcode 5 show resource consumption data at a glance, including CPU, memory, energy use, iCloud, and OpenGL ES. The gauges themselves add very little overhead while your app runs, making it obvious when CPU or memory usage spikes, and alerting you to an otherwise hidden problem long before your users see it. Clicking a gauge reveals a full report, complete with a preliminary diagnosis of what may be plaguing your app. You can then click a single button to launch Instruments, which will immediately begin performing a deeper analysis of your app’s performance.
