我希望这对你有帮助。

suspend fun performAsyncOperation(id: Int): String {
    delay(1000)
    return "Result $id"
}

fun main() = runBlocking {
    val ids = 1..10

    val deferredResults = ids.map { id ->
        async {
            val elapsedTime = measureTimeMillis {
                val result = performAsyncOperation(id)
                println("Task $id completed. Result: $result")
            }
            println("Task $id took $elapsedTime ms")
        }
    }

    deferredResults.awaitAll()

    println("All tasks completed.")
}
