用 --server 参数指定了相同节点？

说实话，这个锅 ubuntu 不好接，毕竟都是 python 的，唯一不同的就是 user-agent 了

def build_user_agent():
"""Build a Mozilla/5.0 compatible User-Agent string"""

ua_tuple = (
'Mozilla/5.0',
'(%s; U; %s; en-us)' % (platform.system(), platform.architecture()[0]),
'Python/%s' % platform.python_version(),
'(KHTML, like Gecko)',
'speedtest-cli/%s' % __version__
)
user_agent = ' '.join(ua_tuple)
printer('User-Agent: %s' % user_agent, debug=True)
return user_agent

如果是用 speedtest 测试的话，是测试节点问题，不要迷信它们，最好自己搞个网盘实际测试一下

@codechaser

其实已经搜出来了，你需要点击“ Code ”，或者“ goto repo:torvalds/linux extension:c ”

@ryd994

大家都流传“ goto 有害，禁止 goto ”，代码里任何时候都不要用 goto，所以我举了一个反例

写汇编也不会 goto/jmp 满天飞，都是跳到 ret 前恢复栈指针的代码，或者和 break 同义
