    这是一个创建于 375 天前的主题,其中的信息可能已经有所发展或是发生改变。
    新安装的 ubuntu,测试上传速度的时候永远无法超过 4m,同样环境安装的 centos 测速可以达到 40m,大概是什么原因呢?

    只有上行有问题,下行可以达到 300+

    无线 or 有线?
    网卡型号?
    使用的驱动程序和版本?
    供应商固件版本?
    内核日志?

    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

    用 speedtest-cli 测试的
    esxi 里直接跟主路由分配的同一块网卡

    使用相同的节点,centos 里测速,wifi 下连接的笔记本测速上行都是 40,只有 ubuntu 里不到 5

    @lidongdong1222

    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

    问题出在 python3 发送的 header 上
