Why do I use the BT download speed so slow?
[Users questions | Browse:27 | Favorites]
Users questions: I use Bitcomet6.0 speeds can usually download speeds for the ADSL512K only 10KB * S be a movie the next afternoon, I ask people who used BT download speed is the normal number? My download speed so slow why, how fix it?
Experts answer: of personal use of B T experience, fast and slow download speeds primarily concerned with the following: 1. 1MADSL network bandwidth if you are online, then the maximum theoretical download speed can only reach 128K bytes * seconds. Here to explain. We usually say how much bandwidth is the amount of units it is "more than Special * s ***", and download speeds we are talking about how much, it's unit is "byte * seconds." In the computer, 1 byte = 8 bits, 1K-byte = 1024 bytes, so 1M download speeds of network bandwidth is up to 1024 * 1024 * 8 = 131,072 bytes * Second, that is, 131072 * 1024 = 128K bytes * seconds. So you can calculate your own bandwidth to download your theoretical maximum speed, course, speed definitely be taller than the actual value is lower because the system and other programs still use some. 2. The system configuration, if by Over calculated your download speed significantly lower than the theoretical value (1M bandwidth, should be able to reach more than 100K download speed, the other can follow this simple math ratio, required not to run other programs need to connect to the network), then there may is a problem with your system configuration. This situation is more Including the emergence of more network machines (in the LAN, the Internet gateway through a proxy server *), the reason may have the following situations. 1) Proxy Server * gateway to limit the speed of the client. This needs to modify the server configuration, increasing the bandwidth allocated to the client or the cancellation of the bandwidth limit . 2) The server does not open the port mapping. If this is the case, the Internet is no way to take the initiative to connect the machine to your machine for you to send data, the speed will naturally slow. This simply opens a server port mapping on it, please specifically how to do online search about, This information is also more. 3) LAN network bandwidth, such as server connections outside the network speed is 10M? Your LAN also?? 0M of. First use of the above calculation, the maximum theoretical download speed can go to 12.8K bytes * seconds. But in the LAN, the communication speed between two machines Probably accounted for the highest available network bandwidth of 1 * 10, ie 10M LAN, assigned to each client's bandwidth is only 1M, then the local area network speeds has become a bottleneck, your download speed up, there is only can reach 128K bytes * seconds. This situation can be resolved: 1 - Increase the speed of your LAN, use the switch 100M 10M * replace the original hub of the hub; 2 - Do not use the client to download to the server to download the software; 3 - If you download large files, documents and great, then several sets of different client files were as long as you do not mind Trouble. 3. Firewall ports used by BT software usually blocked by a firewall, does not allow external connections. Skynet example, you may run into using the BT software to download over time, Skynet's icon shows ***"!***", you keep a log and then view the Skynet, will find that the external connection is Prohibited. Then you can add a TCP Skynet in the rules, open the ports on the BT software monitoring on it. Other firewall software should also be similar. 4. BT download software, download software, there are many problems in this regard should not, unless it is beta software, Bug More, is not stable enough. But I have used BitTorrentPlus (is called the name of it? Most started when BT), speed will always do not increase, 1M of ADSL download speeds only a few K, was replaced BitSpirit, speeds of up to 20 ~ 30K left Right, then open the port mapping, speed can reach 110K * s. By the way, there is a situation in which to download the software itself (such as BitSpirit) also limited the functions of speed, but also need to pay attention to see. Suggest that you use a BT software, they should first take the time to look at this The use of software, especially software, among the "Options" feature, which may hide a lot of mysterious. 5. The other is the seed and download the remaining question of the number of users, fewer seeds, to download the user less, the speed will naturally compare the ugly. This is no way as those who download it, or Give up, or patience to see personal habits.
