As a network worker, I feel that the most troubling problem for me is not that the user told me that the net was broken, but instead told me that he was slow. What's slow? Slow to download things, open the web slowly, open some sites fast, open some of the site slow, open the web slowly, a variety of exotic flowers slow.
A few days ago, a branch of staff told me that they have a slow speed before 10 o'clock in the morning every day, open the Web page slow, but also slow to get dead, but generally after 10 points is normal. After a long period of troubleshooting, it was found to be a problem with DNS. How do we choose DNS as a Web worker or a user? Here I recommend an easy way to select DNS, using the 360 Security defender's "DNS optimization" tool. If you do not download it, you need to download it.

If you have not previously installed the DNS Preference tool, enter the search in search, and then use it after installation.

The following is the 360 preferred DNS results, based on the results using the best DNS.

If the preferred DNS results are still not ideal, you can find some local operators or you think it might be the ideal speed of the DNS, on the local connection manually filled out, the DNS test again, more than a few times, can find more reliable DNS.
