Proxy Server Stress Test_JMeter Simulates High Concurrency Scenarios

Why do I need a proxy IP for stress testing?

When many enterprises test server performance, sending requests directly from the local network will encounter two headaches: first, single-IP high-frequency access is easy to be blocked by the target site, and second, it is not possible to simulate the geographic distribution of real users. At this timeproxy IPIt becomes a necessity - by changing the IP address of different regions, it can avoid triggering the anti-crawl mechanism, but also restore the real user access scenarios.

Taking the server stress test before the e-commerce promotion as an example, using a single IP to initiate 10,000 requests, the server may directly determine that it is a malicious attack. However, if the server is pressurized byipipgoThe global residential IP pool, with 500 IPs from different regions sending 20 requests each, not only protects the security of the test account, but also makes the test data closer to the real traffic.

How does JMeter configure proxy IPs for high concurrency?

Here's one to teach youzero-code configuration methodIt takes only three steps to get JMeter to use a proxy IP:

1. Add "HTTP Request Defaults" to the Test Plan
2. Find Proxy Settings in the Advanced tab.
3. Fill in the proxy server address and port provided by ipipgo.

Here's the point!ipipgo supports full protocol proxies, both HTTP/HTTPS and SOCKS protocols can be configured directly. Especially their dynamic residential IP, each request automatically switch IP, especially suitable for the need to simulate the real user behavior of the scene.

3 details you must pay attention to during testing

First, IP distribution should be scientific:If the test users are concentrated in a certain region, it is recommended to choose ipipgo'sregionally oriented IPFunction. For example, to test the access of Southeast Asian users, you can lock the residential IPs of Singapore and Malaysia.

Second, the switching frequency should be reasonable:Add X-IP-Rotate parameter in "HTTP Header Manager" to set reasonable IP switching interval. It is recommended to change IP every 5-10 requests to avoid too fast switching affecting the accuracy of the test.

Third, protocol matching should be precise:If the system under test has HTTPS encryption enabled, remember to check the "Use KeepAlive" option in the JMeter and use ipipgo'sSSL encrypted channelThe data transmission is secured.

Test case: a video platform stress test optimization

When a team used local IP to test, 200 concurrency triggered the flow limit. After changing to ipipgo proxy IP, the breakthrough was realized by the following configuration:

• Use of 200 US dynamic residential IPs
• Carry 10 concurrent threads per IP
• Setting a 3-second random delay

Eventually it stabilized to 2000 concurrency and successfully detected the server's response delay problem at 1800 concurrency. This kind of real geographically distributed stress test can more accurately expose the load bottleneck of CDN nodes.

Frequently Asked Questions QA

Q: What should I do if I encounter IP blocking during testing?
A: It is recommended to turn on ipipgo'sIntelligent Rotation ModelIt can automatically switch IPs when abnormal status codes are detected, and can be used to set random request intervals to simulate the rhythm of human operation.

Q: How to verify if the proxy IP is effective?
A: Add the "View Result Tree" listener in JMeter and check the X-Forwarded-For field in the return header. If it shows the IP address provided by ipipgo, it means the configuration is successful.

Q: What if I need to test different network environments?
A: ipipgo'sOperator Filtering FunctionCarrier IPs such as AT&T, Verizon, etc. can be specified, supporting simulation of access scenarios for different network types such as 4G/5G/broadband.

Through the rational use of proxy IP service providersipipgoThe technical advantage of JMeter is that it can not only break through the limitations of traditional stress tests, but also obtain more realistic performance data. Next time you do a server stress test, remember to put this "invisibility cloak" on JMeter first.
