pikapython 与lua在fib函数下的对比，VM的效率还有很大的提升空间

平台都是用win10 VS2017编译的pikapython1.13   lua5.3.6  x64 release
----------------------------pikapython1.13代码：------------------------------------
import time

def fib_recursive(n):
    if n <= 0:
        return 0
    elif n == 1:
        return 1
    else:
        return fib_recursive(n-1) + fib_recursive(n-2)

tmstart = time.tick_ms()
fib_recursive(25)
tmend = time.tick_ms()
print(tmend - tmstart)

---------------------------lua代码：----------------------------------
function fibonacci(n)
    if n <= 1 then
        return n
    else
        return fibonacci(n-1) + fibonacci(n-2)
    end
end

function measure_fib_time(n)
    local startTime = os.clock()
    local result = fibonacci(n)
    local endTime = os.clock()

-- os.clock() 返回的是秒数，乘以1000转换为毫秒
    local elapsedTime = (endTime - startTime) * 1000
    return result, elapsedTime
end

-- 示例：计算第30个斐波那契数及其耗时
local result, timeTaken = measure_fib_time(25)
print("Fibonacci(25) =", result, "Time taken:", timeTaken, "ms")

pikapython的vm还有很大的优化空间。。。。。。。。。。。。。。。。
