Proxy IP on the crawler speed impact: proxy IP speed optimization program

How exactly does a proxy IP affect crawler speed?

Let's take a real scenario: you use a single IP to crawl the data at the top of your lungs, but the site is blocked, and after you change to a proxy IP, it's even slower. Don't worry, the problem lies in theAgent Qualityrespond in singingPositions for use。比如某些代理节点超过500ms，或者同时开100个线程把代理服务器搞崩了，这些都会让爬虫变成乌龟爬。

Four Pit Point Self-Inspection Form

A real-world solution to make crawlers fly

Option 1: Dynamic IP Rotation

Automatically switch IPs every 10 requests with ipipgo's Dynamic Residential Package. code example (Python version):

  
import requests
from itertools import cycle

proxies = cycle(['111.222.333.44:8080','555.666.777.88:3128']) List of proxies from ipipgo

for _ in range(100).
    current_proxy = next(proxies)
    try.
        response = requests.get('https://目标网站', proxies={'http': current_proxy}, timeout=5)
        print('Successfully fetching data')
    except.
        print(f'{current_proxy} failed, switching automatically')  

Option 2: Intelligent Dispatch Black Technology

把ipipgo的API返回的代理IP按响应速度排序，优先用＜200ms的节点。实测能提速40%以上。

Option 3: There is a choice of protocols

Don't use HTTP protocol with your eyes closed! Like when you need to transfer images/videos, using Socks5 protocol can reduce the packet loss of 20%. ipipgo backend can switch the protocol type with one click.

Three common questions asked by white people

Q: Is the more proxy IPs the better?

A: Big mistake! 50 quality IPs are better than 500 spam IPs. It is recommended to use ipipgo'sStatic Residential IP, an IP can be used for a full month without flipping.

Q: How do I determine agent speed?

A: The three-step test method:
1. Measurement of basic connectivity with the curl command
2. Send a HEAD request to see the response time
3. Actual capture of small batches of data to see the throughput

Q: Do I have to use a paid proxy?

A：免费代理99%是坑！我们测试过，免费代理平均1.2秒，ipipgo的动态套餐才300ms，价格也就一杯奶茶钱。

Why ipipgo?

Real life experience of having used it in my own home:
1. Work orders raised at 3:00 a.m. are actually answered
2. When bombarded by CAPTCHA, customer service helped to transfer theTK Line
3. Support to buy traffic by the hour, small projects do not hurt!

Speaking human version of the proposal: just start playing with dynamic crawlers with the standard version, to do cross-border e-commerce data monitoring closed eyes into the static package, enterprise-level projects directly to find them customized solutions, can save a lot of money.
