Is it possible to run more than 64 threads simultaneously on one system?

Yes, the system can run more than 64 threads simultaneously. The 64-thread limit is not a strict limit imposed by the operating system or hardware platform. However, the number of threads running concurrently depends on device resources (CPU cores, memory) and OS restrictions. In iOS, as in other systems, hundreds of threads can be created, but too many can lead to decreased performance due to context switching and resource contention.
