ThreadedHTTPServer在任何请求到来之前打开线程

Question

我有一个带有简单ThreadedHTTPServer的python脚本。我在linux服务器上运行它，一旦我启动脚本，在任何请求到来之前，我看到很多线程（~40）。

如何设置服务器启动的线程数的最大值？
如何在请求到达时设置服务器将使用的线程数的最大值？

def add_score():  # let me rename this to lowercase
    ans = []  # lets put the new file content here
    with open("users.txt") as myFile:
        for num, line in enumerate(myFile, 1):
            if name in line:
                line_found = num
                # break -- you don't want to break, you want your 25 to be 26
                *things, num = line.split(": ")  # extract whats after the last ': '
                things.append(int(num)+1)
                line = ": ".join(things)  # change the line
             ans.append(line)
    print("".join(ans), file=open("users.txt", mode='w'))
