Using AJAX to Improve the Bandwidth Performance of Web Applications this article quantifies how AJAX technology can save the Bandwidth of Applications. I compared the results of the two tests in the article with a picture combination: This shows the effect is more obvious. Here are several basic results:1. Applications that contain ajax are downloaded for the first time, which is larger than applicatio
Recently found a problem in the work, with the Linux deployment project, upload code to the public cloud machine, the connection is often interrupted, the operation of the colleague analysis is due to insufficient bandwidth, the workaround is as follows:Add parameters to the SCP command such as: SCP- L 8000 xxxxxx xxx:/sssParameter meaning:-L limit limits the bandwidth that the user can use, in kbit/s. Beca
Run the Nethogs command on the Ubuntu terminal to view the network bandwidth. Nethogs is a network traffic monitoring tool on a terminal. It displays the bandwidth usage of each process, so that the network usage can be obtained more intuitively. It supports IPv4 and IPv6 protocols, local NICs, and PPP connections. Top: You can view the cpu and memory used by processes, and monitor the processes that occu

Managing network bandwidth is becoming more and more important. On a network with no other routers, it makes no sense to route the broadcast traffic that flows out of the network interface. This is very inefficient for your network bandwidth and router resource usage. Let's take a look at how to better bandwidth control by using the Passive-interface command. To

Iperf is a network performance testing tool. Iperf can test TCP and UDP bandwidth quality. The Iperf can measure the maximum TCP bandwidth with multiple parameters and UDP characteristics. Iperf can report bandwidth, delay jitter, and packet loss. Using Iperf, this feature can be used to test the performance of some network devices such as routers, firewalls, swi
Most home users use the ADSL dial-up method to surf the Internet. However, in this environment, once we activate the eMule or BT application, these applications tend to "Occupy" all limited ADSL bandwidth resources without hesitation, so that other network applications cannot run normally. As the application "master" of the program, can we only watch the eMule or BT application forcibly occupy the ADSL bandwidth

At present, most broadband users in China use ADSL as the access method. However, using the ADSL Access Mode to watch IPTV faces the following two challenges: 1. distance problem: the user line ring resistance suitable for activating ADSL service should be less than 900 ohm, and the line length should be less th
