💡 What:
Replaced blocking
Thread.sleepcalls with Kotlin's coroutinedelayinsideLatencySimulator's methods:emulateTeeOperation,emulateStrongBoxGenerateKey, andemulateStrongBoxCreateOperation. The functions were updated with thesuspendkeyword.🎯 Why:
Calling
Thread.sleepdirectly blocks the thread executing the operation. For TEE emulation layers executing on an IO/Main thread or during high concurrent operations,Thread.sleeplimits thread availability, reducing the system's ability to efficiently multiplex. Using coroutinedelayfrees up the thread to perform other work during the delay, providing better resource utilization.📊 Impact:
Non-blocking suspension significantly reduces thread contention and thread context-switching overhead in environments managing concurrent operations, matching standard Kotlin performance practices.
🔬 Measurement:
Given the specific TEE and StrongBox simulations and the lack of existing benchmarks, we verified correctness using the existing functional test suite (
:service:testDebugUnitTest). The theoretical advantage is improved concurrent processing scalability due to released thread locks during sleep time.PR created automatically by Jules for task 2873208313759585067 started by @tryigit
