This article introduces the knowledge of "what is the difference between thread IP pool and traditional dynamic forwarding". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. Work differently: there will be a random IP request and return to the target site.

Regular dynamic forwarding: you need to set your proxy to a fixed server port and then request any target site, there will be a random IP request and return to the target site.

Thread IP pool: each crawler thread can access the corresponding fixed thread proxy port, switch at any time through this interface, or set to automatically switch different output IP, each output IP is real-time.

2. The forwarding server is different: the bottleneck problem can easily affect the performance of the system crawler.

Regular dynamic forwarding: forwarded through a remote server. Because multiple users use a remote server to forward at the same time, the server's concurrency bottleneck, bandwidth bottleneck, CPU bottleneck, memory bottleneck, IO read and write bottleneck and other problems easily affect the performance of the system crawler.

Thread IP pool: forwards through the local client. The traffic transmission efficiency of the thread IP pool is almost limited to your local network, has nothing to do with other users, and is more scientific and efficient.

3. Different billing methods

Traditional dynamic forwarding: some suppliers in the market charge according to the number of tunnels, some charge according to the number of forwarding (number of requests), the price is usually more expensive.

Thread IP pool: it is usually charged by the number of threads, switchable IP and HTTP requests, and the price is relatively cheap. For example, Sun http proxy IP uses thread IP pool, which is more scientific and efficient and more flexible in billing.

This is the end of the content of "what's the difference between thread IP pool and traditional dynamic forwarding". Thank you for reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
