You may encounter many problems in the use of proxy IP, such as proxy IP can not connect normally, or during the normal connection , but the speed is very slow， etc. Here are some reasons why proxy IP is slow.
First, the proxy IP server is in a slow speed of network. When encountering slow speed, the common thought is that there are some problems with proxy IP server’s network. In this case, you need to contact the service provider to solve it.
Second, it may have something to do with the performance of the proxy server. If the proxy server configuration can't handle the pressure of a large number of user accesses, then it is easy for the proxy IP to perform poorly.
Third, long distance of data transmission. Everyone may understand the farther the distance, the slower the speed. The time-consuming is relatively longer because of multiple nodes in transit.
Forth, the target website isn’t working. If the target website speed is not working, it is of no use no matter how fast the proxy IP is.
Fifth, the two factors of network and configuration of users computer may also effect the proxy IP speed. The only way to solve problem caused by hardware is upgrading configuration. If users have problem with their network, it may be slow to access target site even without proxy.
The reason why the proxy IP is slow in daily use is basically the above mentioned. When it encounters, investigate the problems one by one.
