RustPython Slow to Normal Python

[MominIqbal-1234]

Summary

i can check the speed test rustpython and python
but result is not good i think so rustpython create to increase python code execution speed
please can you explain

Currently RustPython is a lot more slower than CPython. Implementing more optimization will improve it.

import time

def test_list_operations():
    lst = [i for i in range(100000)]
    start_time = time.time()
    for _ in range(1000):
        lst.append(len(lst))
        lst.remove(lst[0])
    end_time = time.time()
    print("List operations took", end_time - start_time, "seconds")

def test_dict_operations():
    dct = {i: i**2 for i in range(10000)}
    # 添加键0到字典中
    dct[0] = 0**2
    start_time = time.time()
    for _ in range(1000):
        dct[len(dct)] = len(dct)**2
        # 检查键是否存在，然后删除
        if 0 in dct:
            del dct[0]
    end_time = time.time()
    print("Dictionary operations took", end_time - start_time, "seconds")

def test_loop():
    start_time = time.time()
    for _ in range(1000000):
        pass
    end_time = time.time()
    print("Loop took", end_time - start_time, "seconds")

def test_function_call():
    def dummy_function():
        pass

    start_time = time.time()
    for _ in range(1000000):
        dummy_function()
    end_time = time.time()
    print("Function call took", end_time - start_time, "seconds")

test_list_operations()
test_dict_operations()
test_loop()
test_function_call()

Comparing the running of cpython and rustpython, only function calls are very slow, which may not be tolerable.

PS E:\repositories\rust\RustPython\target\release> python a.py
List operations took 0.038018226623535156 seconds
Dictionary operations took 0.0 seconds
Loop took 0.029998302459716797 seconds
Function call took 0.07699966430664062 seconds
PS E:\repositories\rust\RustPython\target\release> ./rustpython a.py
List operations took 0.03842902183532715 seconds
Dictionary operations took 0.002158641815185547 seconds
Loop took 0.2583482265472412 seconds
Function call took 1.0768907070159912 seconds

But I really like this project because it no longer requires a runtime with cpython, which is great!

Thank you for sharing the insight. One of the missing optimization in RustPython is vector call. It maybe related.
