Platform threads versus virtual threads

“

- [Instructor] The regular Java threads or platform threads that we know of are thin wrappers around OS threads. It takes a lot to create and run platform threads. They require a large stack space and other platform or OS resources. Hence, they are costly to be created and executed. This is because platform threads are mapped one-to-one with OS threads. Despite this overhead of creating and running platform threads, they are easy to program and debug when using the thread-per-request pattern. Thread-per-request pattern means that the platform's unit of concurrency, which is a thread, maps directly to the applications unit of concurrency, that is a request. So each request is handled by a separate thread. However, the thread-per-request pattern limits the amount of requests a system can process in a given amount of time. In other words, the throughput. Due to this, the scalability of the system is hindered. This is…
