Highly Concurrent Crawler IP Solution: Mega Request Throughput Optimization

Practical Guide: Residential IP pools to break through the bottleneck of millions of crawler throughput

When the crawler business needs to handle millions of requests per day, traditional single-server deployment will encounter a fatal bottleneck. Measurement data shows that even if a single server is configured with 100 threads, the average daily request limit is difficult to exceed 300,000 times. At this time, we must use a distributed architecture + high-quality proxy IP combination program.

Core pain points and solution ideas

In highly concurrent scenarios, request failures come from three main levels:

We recommend using ipipgo'sDynamic Residential IP PoolThe real home broadband network environment can effectively circumvent the anti-climbing mechanism, and with the self-developed intelligent scheduling system, it can automatically match the best exit nodes.

Distributed Architecture Building Essentials

A master-slave architecture is recommended:

1. Scheduling server: responsible for task distribution and IP pool management
2. Cluster of worker nodes: at least 5 servers deployed
3. IP Pool Service: It is recommended to call ipipgo's API interface directly, their residential IP pool contains90 million+ real IP resourcesSupport for on-demand dynamic calls

Example of key parameter settings:

 Single working node configuration
Maximum concurrency: 200
Duration of single IP use: 3-5 minutes
Failure retry times: 3 times
Request interval float: 0.5-1.5 seconds

Intelligent Dispatch System Design

The following functional modules are proposed to be implemented in the scheduling layer:

• IP Quality Scoring System: Dynamically adjust weights based on response rate, success rate
• Geographic scheduler: automatically assigns local residential IPs for region-specific requests
• Protocol adapter: support HTTP/HTTPS/SOCKS5 full protocol switching

API support for ipipgoPrecise geographic filteringFunctionality to specify city-level IP assignments, which is especially important for crawler projects that need to simulate the distribution of real users.

Practical QA Analysis

Q: How can I avoid IP bans in bulk?
A: Adoptiondynamic rotation strategyWith a single IP usage time limit of 5 minutes, ipipgo's residential IP pool provides millions of unduplicated IP resources per day.

Q: What should I do if I encounter a surge of CAPTCHAs?
A: Immediately switch the IP type and adjust the data center IP to residential IP. ipipgo supporthybrid IP modelThe CAPTCHA defense can be broken by automatically switching between different IP types.

Q: How do you ensure data collection integrity?
A: Establish a three-tier retry mechanism: instant retry (same IP), delayed retry (change IP), and manual verification. Cooperate with ipipgo'sRequest Success Rate Guarantee ServiceThe IP group can be designated as highly available for business-critical operations.

Through the reasonable architecture design and ipipgo professional proxy services with, we have helped many enterprises to achieve a daily average of 8 million + requests stable operation. It is recommended to first pass theFree TrialTest the adaptability of specific business scenarios, and then gradually expand the cluster size.
