Apple har släppt ett nytt utvecklarverktyg kallat Xray. Programmet håller koll på systemprestanda så att utvecklare kan se hur deras applikationer påverkar RAM, hårddisk och processorn.
Beskrivning: Record the application’s behavior in Xray, change your code, and rerun the tests to see the effect of your changes. Run your application in a template and Xray visually compares the runs side by side, making it clear where your code changes affect performance or memory consumption.
Xray includes analysis instruments in six main categories:
* User events. Tracks the exact time of user interactions, such as mouse clicks.
* CPU and processes. Monitors activity, sampling, load graphs, and threads.
* Memory. Tracks garbage collection, object allocations, and leaks.
* File activity. Monitors disk activity, reads and writes, and file locks.
* Network activity. Measures and records network traffic.
* Graphics. Interprets the inner workings of the OpenGL driver.
