Kotlin coroutine

Hi do you know how do I proceed to have my coroutines run on different threads? I have tried this to speed up: 
val threadPoolExecutor: ExecutorService = Executors.newFixedThreadPool(3)
val coroutineDispatcher: CoroutineDispatcher = this.threadPoolExecutor.asCoroutineDispatcher()

withContext(coroutineDispatcher) {
    dependencies.forEach { dependency ->
        val resolver = resolvers.first { resolver -> resolver.accept(dependency) }

        launch { resolver.resolve(dependency) }
    }
}
val threadPoolExecutor: ExecutorService = Executors.newFixedThreadPool(3)
val coroutineDispatcher: CoroutineDispatcher = this.threadPoolExecutor.asCoroutineDispatcher()

withContext(coroutineDispatcher) {
    dependencies.forEach { dependency ->
        val resolver = resolvers.first { resolver -> resolver.accept(dependency) }

        launch { resolver.resolve(dependency) }
    }
}
but it tourned out it was less fast than concurrent only?

I believe the purpose of kotlin coroutines is not to make your application faster, but so it would make your application responsive and prevent blockages. try increasing the number of threads in the pool or, if you're in Java 22, you can use Project Loom or lightweight threads.
