Speed is generally divided into download speeds and upload speed, generally we calculate the speed is only test download speeds, as long as the computer downloads from the Internet faster, users are usually more satisfied. But you know what? Upload speed is also noteworthy,

enough to look at some of the software, or it doesn't make any sense. The most scientific way is to compare the law. We can test two of people's broadband, for example, AB two are the same place, and are independent users of telecommunications. Then we can observe the two users, download the same resources at the same URL location to see who is fast and who is slow.
As shown below, we can see that th

In general, the fourth method is the most stringent, you can simulate the insert operation of the database, so very slow, but also used to test the performance of the VPS hard drive a benchmark, in general, test r
Test ajax locally to receive paging data. The response should be around 1 S (above) but is there any good solution between 900 ms and ms on the server to solve the slow ajax acquisition speed? The paging data has been changed to json. The data size is not much improved. The display time is kb and the processing time is 1.03s. logic...
Local test AJAX receive paging data to reflect about 1s (above) but on the server on the 100ms to more than 900 Ms What is the best way to solve the Ajax acquisition speed is slow? There's not much improvement in converting paging data to JSON.

The boot speed becomes one of the criteria for judging the performance of computer systems. Slow response systems not only delay time, but also affect mood. Microsoft's WIN8 system has been released for half a year, the following we will compare the Test win and Win8 speed, to see if the Win8 on the boot

Speedtest is an open-source software for testing network performance, and installing Speedtest under Linux can be used to test the upload and download speeds of network exits and help troubleshoot network failures.
Speedtest Introduction
Due to the company several project users to visit when the response is slow, the project itself is not a problem, the service and call the interface return inform
value on the line. If your CPU has DRNG features, you can take advantage of the hardware to increase the speed of the entropy pool. by Cat/proc/cpuinfo | grep Rdrand can see if its CPU is supported, and generally Intel's CPU for the Ivy_bridge architecture is supported (i3, i5 need to be aware of that architecture, i7 and Xeon are basically supported), and AMD's CPUs are supported after 2015. (If you are a virtual machine you need to turn on addition
speed is as follows:
From this, we can find that the best speed is telecommunications, reached the 120k/s, the other is relatively low, because the network is 2M telecommunications broadband, so look at telecommunications is the most accurate, which can be seen faster than 100k, between 100k-200k, from this can also be seen that the speed is 2M.
Let's test the network speed, which php does. It is definitely not an advertisement. you can help test the speed: http://www.hjsww.com.cn thank you. It is definitely not an advertisement. good = thinking is more important than skill =. I use AD, and the open speed is average
When Internet speed is found to be slow, people usually first test their computer to the network service provider (often referred to as the "last kilometer") network connection speed. In websites that can be used to test broadband speeds, speedtest.net may be the most widely
