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+

| 4 liuxu Nov 30, 2018 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 liuxu:~$ speedtest Retrieving speedtest.net configuration... Testing from China Unicom Beijing (114.249.28.210)...

| 6 lidongdong1222 OP @liuxu 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 |
| 7 liuxu Nov 30, 2018 @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 |
