Here requirements in the Thunderbolt 7 or higher to support the speed test function Oh, otherwise please upgrade your Thunder tools.
1, we open the Thunder after clicking on the main page above the
2, and then we'll see a tab with the typeface of a gadget to click on it as shown
4, then we find the middle of the option, write the Speed
Program | script | speed | As mentioned earlier, we can only optimize if we find code that affects speed. The Benchmark_timer class and Benchmark_iterate class in Pear's benchmark package can be used to easily test the speed of script execution. (For the installation and configuration of pear, please check the relevant
The use of wireless routers, computers or notebooks, mobile phones and other speed can not achieve the speed of telecommunications broadband. For example, your broadband from the telecommunications application for 12M, the use of routers after the test speed value of only 4 m, then need to do the following troubleshoot
I. Use the hdparm commandThis is a command used to obtain the parameters of the ATA/IDE hard disk, hdparm has been written by Mark Lord, the primary developer and maintainer of the (E) IDE driver for Linux, with suggestions from javasnetfolk ). this command should also be used only for Linux systems. For UNIX systems, ATA/IDE Hard Disks may be used less often. Generally, large systems use disk arrays.Easy to use# Hdparm-Tt/dev/sda
/Dev/sda:Timing cached reads: 6676 MB in 2.00 seconds = 3340.18 M
Linux dd command to test the read/write speed of the USB flash drive and the dd read/write speed
1. Brief description of the dd command:
If = input file, of = output file, ibs = number of bytes read at a time, obs = number of bytes written at a time, bs = set the number of bytes read and write at a time, skip = number of bs skipped, count = number of copies

Lan network performance test method HDtune 64K has a cache speed test method, let you know your network performance, hdtune64k
This method can effectively test the network transmission performance. This method is applicable to disks, diskless (System Virtual Disk), game Virtual Disks, and other virtual disk software wi
brakes to control the speed, when the front of the left side of the big "4" alignment road is central when parking . handle brake → pick up → turn right turn light → stall → loose clutch → loose brake → loose seat belt. Note: The principle is not to obstruct the traffic section parking. Junction within 20-30 meters , red light junction 50 meters , Bus station, Crosswalk Line, school area, fire tunnel, gas station, etc. no parking .④ report: The exam
◆ Script Execution speed test
As mentioned above, we can only optimize the code that affects the speed. The benchmark_timer class and benchmark_iterate class in the benchmark package of pear can be used to conveniently test the speed of script execution. (For installation an

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 the download
Recently many friends discussed about how to test the speed? We have given a lot of test speed method, such as the common use of downloading things to determine the download rate to judge the speed of the network, and also have friends said that using online network
all on a disk, this command is equivalent to the test disk's simultaneous reading and writing capabilities
Here are a few common DD commands to see the difference

$ sudo pip install speedtest-cli --upgrade
Install SPEEDTEST-CLI via Pyhton scriptFirst, use the wget command to get the Python script from GitHub, then extract the downloaded file (master.zip)
$ wget https://github.com/sivel/speedtest-cli/archive/master.zip
$ unzip master.zip
After extracting the file, go to the extracted directory speedtest-cli-master and make the script executable.
$ cd speedtest-cli-master/
$ chmod 755 speedtest_cli.py
/sec;Read 218MB disk (physical read) in 3.11 seconds, read speed approx. 70.11 mb/sec(2) using the DD commandThis is not a professional testing tool, but if the test results are not very demanding, you can usually use to make a simple evaluation of the disk read and write speed.In addition, because this is a free software, basically Xnix system is installed, for the replication of Oracle bare devices, DD to
The current mode of mechanical disk operation, mainly reflected in the disk reading and writing to find the track of the process, the disk caching function for reading and writing speed is very important. Disk search process is a mechanical way, so that its random speed is significantly lower than the sequential reading and writing, generally ordinary disk IO can reach 40--60MB per second, slightly better w
