Everyone can also use the TCPA developed by Tencent on a daily basis. Its effect is similar to that of BBR, and it has been optimized for site use. The installation and introduction of TCPA can be viewed: One-click to open Tencent version of the BBR-TCPA installation tutorial and comparison with Google BBR PLUS 4: Preparations

Due to the complex and changeable international network environment, the network quality of international lines is easily unstable. In order to improve the network throughput of VPS, increase the availability of VPS, and speed up the network transmission speed, Kaixin Xiaozhuo recommends that you install the TCP acceleration software BBR developed by Google or the modified BBR PLUS when using non-mainland VPS. It is recommended to use the TCPA developed by Tencent.


BBR has been installed in this test. In fact, if you want to store large files, you can choose to install Rui Su. Those who do not install BBR PLUS can view: centos install BBR, BBR magic revision, BBR violence magic revision, BBR PLUS, sharp speed video tutorial

Five: test environment

This test is the vps of the Hong Kong Shatian Fotan computer room of the coffee host. The specific configuration is 1 core 1G memory 2M bandwidth 50G hard disk. On the official website of the coffee host, the price is 26 yuan/month. The price is 18.2 after using the discount code 2020NEW30 Yuan/month, equivalent to 2.5 USD/month.

The local network is Henan Unicom’s home width, 100Mb/s down and 20Mb/s up.

The test time is April 11, 2020, at 22:00.

Seven: Script to view basic server information

----------------------------------------------------------------------
 CPU Model            : Intel Xeon E3-12xx v2 (Ivy Bridge, IBRS)
 CPU Cores            : 1 Cores 2394.230 MHz x86_64

 Total RAM            : 436 MB / 984 MB (167 MB Buff)
 Total SWAP           : 0 MB / 511 MB

 Organization         : 
 Location             : Beijing, China / CN
 Region               : Beijing
----------------------------------------------------------------------

Through the script test, you can see that the script tested is also a 1-core CPU, the CPU frequency is 2.4Ghz, and in terms of VPS, the CPU cache is 4096KB.

The form of virtualization is the kvm architecture. The location displayed at the bottom shows Beijing, which is wrong, it should be the IP positioning of the script is wrong, the real address is Hong Kong.

Eight: Script to test hard disk speed

I/O Speed( 1.0GB): 73.4 MB/s

I/O Speed( 1.0GB): 124 MB/s

I/O Speed( 1.0GB): 82.8 MB/s

Average I/O Speed: 93.4 MB/s

The three hard disk read speeds measured were 73.4MB/S, 124MB/S, 82.8MB/S, and the average was 93.4MB/S.

Nine: Speed test

Speed test refers to testing the speed measurement nodes from VPS to domestic telecommunications, China Unicom, and China Mobile, the actual available bandwidth; and the size of your local bandwidth.

The larger the value tested, the better.

note:

1: Since the download speed from the VPS to the speed test node and to your local network is a gradual increase process, the script test set time for each node is relatively short, you can think that the bandwidth of the script test is burst bandwidth, that is The short-term bandwidth, the bandwidth that the speed has not fully increased. Users who use vps to set up a website should pay more attention to the bandwidth of script testing, because the loading process for users to access a web page is only a few seconds, and it is impossible to wait for your bandwidth to fully increase, that is, burst bandwidth plays a decisive role.

2: If your VPS is used to store files, the actual use is for a long time, the use of large bandwidth, you should pay more attention to the bandwidth measured by HTML5 SPEEDTEST.

9.1 Script test return bandwidth

----------------------------------------------------------------------
Node name Server upload speed Server download speed Delay
 Beijing 5G   CT  2.03 Mbit/s       3.92 Mbit/s         42.24 ms    
 Nanjing 5G   CT  2.00 Mbit/s       3.84 Mbit/s         33.32 ms    
 Guangzhou 5G CT  1.90 Mbit/s       4.03 Mbit/s         9.18 ms     
 TianJin 5G   CU  1.95 Mbit/s       4.05 Mbit/s         108.52 ms   
 Guangzhou 5G CU  1.88 Mbit/s       4.13 Mbit/s         62.58 ms    
 Tianjin 5G   CM  2.05 Mbit/s       3.86 Mbit/s         51.59 ms    
 Wuxi 5G      CM  2.03 Mbit/s       3.89 Mbit/s         41.04 ms    
 Nanjing 5G   CM  1.91 Mbit/s       4.16 Mbit/s         57.86 ms    
 Hefei 5G     CM  2.00 Mbit/s       3.82 Mbit/s         57.70 ms    
 Changsha 5G  CM  2.03 Mbit/s       3.96 Mbit/s         31.01 ms         
----------------------------------------------------------------------

CT refers to China Telecom, CU refers to China Unicom, and CM refers to China Mobile. Through the script speed measurement, you can see that the speed measurement bandwidth of the three networks can basically run up to the 2Mbps bandwidth advertised by the business!

9.2 HTML5 test return bandwidth

咖啡主机:7折优惠码  香港沙田BGP线路VPS月付14元起 1核心512M内存2M带宽测评

Through the Html5speedtest speed test program, the effective bandwidth from this coffee host’s Hong Kong VPS to my local Henan Unicom is about 1.97Mbps on average.

9.3 Web page opening speed test

咖啡主机:7折优惠码  香港沙田BGP线路VPS月付14元起 1核心512M内存2M带宽测评

I put the homepage html of the happy webmaster iloan.pub and the pictures, js, css, etc. used on the homepage on this vps for testing. Pay attention to the bottom of this dynamic picture. There are a total of 33 requests, the overall loading size is 512KB, and it took a total of 2.36 seconds to complete the loading of the entire page.

Ten: National PING test delay

The Ping value is the most intuitive value to check the delay between the local network and the VPS. The larger the Ping value, it proves that the longer the data transmission distance between the local network and the VPS, the greater the delay.

Happy webmaster believes that users who build websites facing the mainland should control the Ping value within 200ms, so that users won’t feel obvious lag when they visit your website. Note that the PING value you measured is only the delay from your local to the VPS. VPS sending data to your local is another delay. If the PING value is above 200, the sum of the Ping value back and forth will be close to 0.5 seconds, and there will be a significant delay in the user experience.

If the Ping value is within 50ms, the round trip adds up to 100ms, and the user basically does not feel the delay, and the actual experience is better.

The smaller the Ping value, the better.

咖啡主机:7折优惠码  香港沙田BGP线路VPS月付14元起 1核心512M内存2M带宽测评

It can be seen through the display of the Ping value graph. Most of the country is green. Dark green means that the delay is within 50 milliseconds, and light green means that the delay is within 100 milliseconds. You can also see from the table data that the delay of China Telecom is 40.9 milliseconds and that of China Unicom is 40.2 milliseconds. The delay of the movement is 32 milliseconds. There is no significant difference between the delayed PING value data and the use of mainland VPS.

Eleven: Route tracking:

Route tracing can easily check which routes have passed between your local network and the VPS, and which routes have actually been taken.

Route tracking is divided into outbound and return trips, that is, to test the route that the data takes when you visit the VPS locally; and the route that your VPS sends data to your local network.

Normally, the situation of outbound routing and return routing is similar, and some optimized routes may be quite different.

Through route tracking, we can see that the iconic IP segment 59.43 appeared in the 9th hop of Xuzhou Telecom’s line, indicating that the telecommunications line to this Hong Kong server took the telecommunications CN2 GIA line. It can be seen from the test result that the line is directly connected and there is no detour to the third place.

By observing the routing information, it can be seen that Shandong Unicom passes through the seaport of Shanghai Telecom, leaves the country, and then arrives in Hong Kong. The overall line is a direct connection line. I took the CN2 GIA line of China Telecom.
