Why is the US server so slow, sometimes fast and sometimes slow.

What causes the US server to slow down?

1. Local network issues.

If we suddenly find that it is slow and stuck when we visit. The first thing we need to do is to check if there is a problem with our local network environment. You can use the ping of a well-known domain name, after the ping value comes out, if the ping value is large, it may be that there is a problem with your local network environment.

On the other hand, if the ping is small, there is a problem with the US server.

2. Problems in the computer room.

**If the loading speed is too slow, if you confirm that there is no problem with the local network, it may also be that the problem occurs in the computer room where the US server is located, and the equipment in the computer room is perfect, but it cannot avoid the abnormality of the computer room. When the computer room is maliciously attacked, it will also cause the US server to slow down. In addition, check whether the backbone network of the data center is abnormal.

3. International routing of operators.

Problems with the network we use, the routing of the carrier, or the services provided can also cause the US server to slow down. In particular, our users who use servers in the United States abroad often encounter this kind of problem. When data is lost or routes cannot be connected during data transmission, the US server that uses this type of network cable will be very slow.

This is not a problem with the US server itself, nor is it a problem with the local network, just wait for the operator to fix the network.

Four: Insufficient resources and poisoning of US servers.

We need to know that when the remaining space on the US server is insufficient, the CPU or memory will be overloaded when the program is running, causing the US server to slow down. If you encounter this type of problem, we can try to optimize the system and turn off the software and programs that are not necessarily running on the US server. If this happens frequently, then it's time to upgrade the overall configuration of the US server.

In addition, malicious attacks on the US server will also cause the US server to slow down. Therefore, it is also very important for us to choose the firewall of the US server and the security level of the computer room where it is located.

1. I think it's normal for the server to access the United States from Chinese mainland to be slow, and the export bandwidth is limited.

2. The stability of the server and the computer room are inseparable 3. Suitable for the counterpart telecommunications and Netcom problems. A good IDC is the key, it must be foreign, don't rent a server that changes hands back, it will be very troublesome. Recommend you to search for the Canadian-Chinese general network.

Just in the first place.

The United States itself is slow.

The fastest in Hong Kong, I use the Hong Kong host of Xiluo, you can go and see it, and you can Xiluo yourself.

Due to the lack of China's international export bandwidth, the entire country is less than 50G international bandwidth, which is not as good as more than 1 10 of a university in the United States, which leads to the average bandwidth to each ** site.

Therefore, the speed of visiting foreign space in China will be much slower than that in domestic space. Similarly, when accessing a domestic host abroad, the speed will be slow. Many enterprises will encounter various network problems such as slow network speed and disconnection, especially some international enterprises, which often need cross-border and cross-regional network collaboration, and often face slow file transfer, ERP access timeout, and even web pages cannot be opened.

Generally, there are two ways to solve the problem: 1. Use China Unicom Telecom's private line, which is accelerated through physical links. Specifically, you can consult the salesman, this kind of ** is more expensive, and ordinary enterprises may not have much budget.

2. Use the private line provided by the enterprise, which is accelerated through the virtual private line. At present, Algoblu's SDN plus old fiber speed line is used more often. It is recommended to use SDN if you can use a virtual network to solve the problem, and the physical link** will be more expensive.

You can take a look at the SDN acceleration used by Algoblu. Hope mine is helpful to you.

1.Replace your own network.

As the saying goes, a slap can't be slapped, sometimes it's not someone else's problem, but it may also be a problem of your own network. If you have a good Huaiyuan condition, if you are using telecom broadband upload speed is slow, then you can change to Unicom broadband to upload, and it is likely that the upload speed will be fast.

2.Use a switching line.

By switching the line, switch the line to the closest place to the server, which may be very fast in terms of access speed and upload speed.

3.Package the friendly data and upload it.

The slow upload speed may be due to the fact that the file is too large, so you can package and compress the file before uploading. It's better to upload a small file than a large one. After uploading, you can unzip it.

4.Give the file** to the space dealer and ask them to upload it.

If the uploaded file after packaging is still very slow, then upload the compressed file to the domestic space first, and then send the address of the compressed file to the US server provider, so that they can go to the US server to **decompress.

Due to the lack of China's international export bandwidth, the entire country is less than 50G international bandwidth, which is not as good as more than 1 10 of a noisy university in the United States, which leads to the average bandwidth to each ** site. Therefore, the speed of visiting the country in the domestic space will be much slower than that in the domestic space. Similarly, when accessing a domestic host abroad, the speed will be slow.

Which server in the US are you using? Recently, the export network of domestic telecommunications has not been very stable.

3gipv6 vpn has good servers, you can take a look, search for 3gipv6 The first one is.

1. No filing is required.

In China, the industrial and commercial bureau is very strict about the audit of the first part, and there are many rules, many of which often fail to pass the audit, which is really helpless for users, after all, they rely on this to make a profit. It is recommended that this part of the user can choose the US server, you can omit this step, and only need to parse and bind **.

2. Provide Windows and Linux operating systems.

The US server supports dual systems, and the specific needs to stand on the ** program. If your program is built by ASP, it is recommended to choose Windows operating system. If it's a PHP program, both operating systems are fine.

The two operating systems mentioned here refer to Windows and Linux. It is recommended that you choose the ** PHP program, you can use the Linux system, the interface is easy to understand, and novices can also understand it quickly, without too much technical content.

3. Fast speed.

The US servers are located in some well-known data centers in the US, so you don't have to worry about speed. Moreover, the broadband resources in the United States are so abundant, there are some hosts that have no traffic and broadband restrictions, which is enough for you to use for many years.

4. Strict management of the computer room.

The U.S. server is strictly managed for the data center, and only professionally trained personnel can carry out data room maintenance. And to provide users with 24-hour after-sales service, as long as you have a problem, immediately respond, the other party will give you a set of solutions, you follow the actual operation to do. At the same time, the machine room is also well maintained.

The advantage of the US server is that the bandwidth is large, the IP is more and the restrictions are less, and the disadvantage is that it is far away from the country and the latency is higher, about 180.

Just like you said that the server is in the United States, the advantage of domestic use is that there are fewer restrictions, no need to file, and the disadvantage is also obvious, that is, the distance is long, and the speed will be slow. However, the main purpose of many webmasters is not to use the record, domestic servers need to be recorded, and the record takes time and needs to prepare all kinds of materials, and many webmasters choose the host in Hong Kong or the host in the United States.

There are many reasons why the US server is slow. It depends on the situation.

1. The access speed of the US server is very remote.

Generally speaking, the farther away the user's access is from the server region, the slower the access speed. Therefore, the choice of server is generally decided according to the region where the user accesses. If the US server is for US users, it will be very fast.

However, if mainland users want to access the U.S. server, or U.S. users access the domestic network through the U.S. server, the speed will be much slower, and the normal speed range is about 100ms.

2. The access rate of the US server is related to the bandwidth

If the U.S. server accesses the mainland direct line, that is, China Telecom's export line, the access speed will be much faster than that of the ordinary line. Because ordinary lines may go around long distances, the transmission rate over long distances is slow.

In addition, if the traffic is too large and the bandwidth is overloaded, it is also very likely to slow down the response speed of the server, and increasing the server bandwidth can speed up the network at this time.

In addition, the slow access speed of the US server may be due to a network failure in the server room or an attack on the server. If this happens, you need to contact the service provider of the US server, and it is best to connect with professional operation and maintenance personnel, so that they can investigate the cause of the slow access speed of the US server.

First, the distance factor.

We know that the distance of the server data center will have a very big impact on the opening speed. The opening speed of the same site is different in different regions. If the server is too far away, there will be more nodes in the middle, and when the user sends a request, it will pass through many nodes, and after the feedback is over, the entire network latency will be very long, and the opening speed will be relatively slow.

Generally speaking, if this situation occurs, CDN acceleration is selected to solve this situation.

Second, the performance factor.

Some products don't perform well enough to also lead to the overall speed of access. Now there are more server products on the market, and the quality is not the same, there are good and bad, uneven, if the user buys the product quality is not good, the performance of this server can not keep up with the demand, and it will be greatly affected when it is opened. Therefore, to eliminate the performance factor, it is best for us to choose a large brand server provider before buying an overseas server.

Third, the visitor factor.

** has been running optimally, then it will also have more and more visitor traffic, when it reaches a certain value, it will be crowded, if this is the case, you can upgrade the server**. For more information, see Host Detective.
