Proxy IP Concurrency Optimization: Connection Pool Management and Multiplexing Techniques

Why is your crawler always being counter-crawled? Maybe you don't understand connection pooling

Engineers who do data crawling have encountered such a scenario: obviously changed the proxy IP, the target site is still frequently blocked. The problem often lies in theConcurrent connections are not scientifically managed. Like traffic at an intersection during rush hour, if a new connection is created for every request, it quickly results in a run on IP resources.

Hands-on connection pooling tips

Using ipipgo's dynamic residential IP as an example, it is recommended to press the3:1 ratioSet up the base connection pool:

Be careful with the specific configuration:

1. Individual session objects per IP
2. set up10-15 secondsidle timeout
3. Automatic isolation mechanism for abnormal IP

Three hidden hurdles in multiplexing technology

Many people think that reuse means reusing IP, but there are actually three key points to break through:

1. Protocol adaptation

ipipgo supports socks5/http(s)/socket full protocol, but the actual use of the websocket protocol multiplexing connection, the success rate is higher than http 27%

2. Heartbeat preservation

It is recommended to send TCP keepalive packets every 90 seconds, which is measured to extend the effective length of IP by 40%.

3. Requests for fingerprint confusion

When multiplexing the same IP, create different request characteristics by randomizing request headers, encrypting parameters, etc.

Dynamic/static IP selection strategy

Select resource types based on business scenarios:

Frequently Asked Questions

Q: What is the appropriate connection pool setting?
A: Recommended formula: base number = expected peak concurrency / (single IP carrying capacity × 0.6). ipipgo single residential IP recommended carrying capacity in 3-5 times / second

Q: How many times does IP reuse need to be replaced?
A: Dynamic IPs are recommended to be reused no more than 15 times in a single task, while static IPs can be reused more than 50 times. For details, please refer to the IP health tips in the ipipgo console.

Q: How can I detect if an IP is tagged?
A: Recommended three-step testing method: 1) check the response status code 2) parse the page feature words 3) test the success rate of the regular interface. ipipgo provides real-time availability monitoring interface

Through scientific connection pool management and reuse strategy, together with ipipgo's global residential IP resources, it can effectively increase the business success rate to the industry leading level. It is recommended that developers complete a stress test during the free trial phase to find the most suitable configuration parameters according to specific business scenarios.
