+
+ | Aspect |
+ Multithreading |
+ Multiprocessing |
+
+
+ | Memory Usage |
+ Less memory usage/Shared memory space |
+ More memory usage/Separate memory space for each process |
+
+
+ | Concurrency Type |
+ Concurrent threads within a single process |
+ Parallel processes with separate memory spaces |
+
+
+ | GIL Impact |
+ Affected by GIL (only one thread executes Python code at a time) |
+ No GIL; multiple processes can run Python code simultaneously |
+
+
+ | Best For |
+ I/O-bound tasks (e.g., web scraping, file I/O) |
+ CPU-bound tasks (e.g., heavy computations) |
+
+
+ | Synchronization |
+ More complex due to shared state |
+ Less complex but requires IPC for communication |
+
+
+ | Overhead |
+ Lower overhead, but limited by GIL |
+ Higher overhead due to process creation and management, but no GIL limitation |
+
+
+ | Fault Isolation |
+ A thread crash can affect the entire process |
+ A process crash is isolated to that process |
