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. For example, if some proxy nodes have a latency of more than 500ms, or if 100 threads are open at the same time to crash the proxy server, these can turn the crawler into a turtle crawl.

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

Sort the proxy IPs returned by ipipgo's API by response speed and prioritize nodes with latency <200ms. The actual test can speed up 40% or more.

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: The free agent 99% is the pit! We have tested, free proxy average delay 1.2 seconds, ipipgo dynamic package delay is only 300ms, the price is also a cup of milk tea money.

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.
