The slow ping response of ubuntu solves the problem that the Internet access is always slow after ubuntu is installed. It takes a long time for the ping command to respond to the ping request, but the network latency is normal. Later it was found that it was because of/etc/nsswitch. if there is a problem with the hosts configuration in the conf file, make the following changes: change the original hosts: files mdns4_minimal [NOTFOUND = return] dns mdns4 to hosts: files dns without restarting, now ping is normal.
