Use ETags to reduce Web application bandwidth and load by 12th pages. Recently, the public has been strongly interested in the REST-style application architecture, which indicates that the elegant design of the Web is being noticed. Now, we gradually understand the "3 W Architecture (Introduction to Arc Recently, the public has been strongly interested in the REST-style application architecture, indicating that the elegant design of the Web has begun

I have been testing Double dial 1 recently. The first Double dial, hence the nickname, is that a single number is used twice and used twice at the same time to obtain the upload and download bandwidth of the two parts. Currently, no. 1 dual-dial can be used in many cities. This seems to be achieved by exploiting the vulnerability, namely two virtual pppoe interfaces and dialing using the same account password. Double dial 1 does not mean that after s

Recently the company server bandwidth suddenly increased, server load is not very high, CPU and memory are not high ah, why the bandwidth is high ah, ask you to help analyze the expert!

Because many VPS or server are limited traffic, but many service providers do not provide a detailed flow chart, such as daily traffic table, so it is certain that some people would like to know how much traffic on their servers.Vnstat is a very useful server traffic statistics command. I'll get a few pictures to show you.Statistics days and month of statistics:is not very intuitive. Let's take a look at how this command is used. Estimated is the meaning of estimating usage.

Due to the company's troubleshooting needs, it is necessary to record and save the high bandwidth-consuming processes or ports on the public server, so that you can check the problem later.This problem tangled 1, 2 days, the use of Python should be able to meet the needs, but the novice python is not to take the shot, so can only rely on the Linux finished gadgets and Shell to achieve.Linux iftop and nethogs two tools to meet the requirements, but nei

Failure phenomenon: Video viewing is not smooth, the occurrence of screen delay and the situation of Carrington. Reason Analysis: This is generally related to the speed. Solution: Lenovo Wireless video service using high-definition cameras from the home network to upload video streaming to the internet for mobile phones and PCs to watch, need at least 512kbps uplink speed, in order to get a better viewing effect. At present the carrier provides ADSL broadband for up and down row asymmetric

Special contact with the computer room, because the original line can not upgrade the bandwidth, so only to change the IP and upgrade the bandwidth, thanks to the support of Shanghai sentient beings, let us save a lot of trouble, and successfully resolved the site can not access the problem.

How does a router limit the speed of a LAN, how does the LAN allocate network bandwidth, and Control LAN traffic? The following two methods can be used to limit the network speed of a computer and prevent the network speed of a LAN:1. Methods of limiting others' network speeds, controlling the network speeds of other computers, and limiting lan network traffic through RoutersThe specific method is as follows:1.

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

cinema, even if everyone is willing to watch the movie at your turn, so what is the use of the Internet? What is the use of high bandwidth? It seems that there is no disease. Since the development of the Internet in China, we can look at the positive side. However, such an approach is not recognized by many people. There are advantages and disadvantages in the Development of everything. From the perspective of the industry chain, film and television
