![]() But also increases process management overheads as multiple processes are heavier than multiple threads. Multiprocessing increases the performance of the program as each Python process gets its own Python interpreter and memory space so the GIL won’t be a problem. This is the reason why the global interpreter lock is required. Also, threads use the same memory so precautions have to be taken or two threads will write to the same memory at the same time. Multithreading does not make much of a difference in execution time as it uses the same memory space and a single GIL, so any CPU-bound tasks do not have an impact on the performance of the multi-threaded programs as the lock is shared between threads in the same core and only one thread is executed while they are waiting for other tasks to finish processing. To make our python programs run parallel we use multithreading and multiprocessing. Each core in the CPU has its own GIL, so a quad-core CPU will have 4 GILs running separately with its own interpreter. The default implementation of Python ‘ CPython’ uses GIL (Global Interpreter Lock) to execute exactly one thread at the same time, even if run on a multi-core processor as GIL works only on one core regardless of the number of cores present in the machine. Let’s look at the reasons why Python is much slower compared to these languages and what can we do to increase its execution speed. We all know that Python is much slower than statically-typed programming languages like C, C++, Java and some dynamic languages too like JavaScript and PHP. #21- Astounding Stories of Super-Science June 1931: VOL.#20- Every Resident Evil Game in Chronological Order: A Complete Timeline.#19- The Metro Games in Chronological Order: A Postapocalyptic Masterpiece.#18- The Batman Arkham Games in Chronological Order.#17- 5 Best Pokémon GO Hacks and How to Get Them.#16- How Do I Build High-Volume dApps With Ultra-Low Gas Fees?
