Proxy Manager Performance Test Report: Concurrency Handling and Stability Comparison

First, why is your crawler always stuck in the agent manager step?

Recently encountered a number of friends complained that the use of proxy ip to do data collection, the program ran and ran on the card death. In fact, this matter is directly linked to the performance of the proxy manager, just like listening to the radio with an old-fashioned radio, channel tuning more than the machine on the hot strike.

Let's take the three most common scenarios and test them:

II. Testing methods for real gold

Don't believe those fancy test reports, I'll teach you a dirt cheap way:Open three browser windowsI'm trying to access different websites in different regions at the same time. The left window hangs a normal proxy, the center with ipipgo, the right does not hang a proxy. Repeatedly refresh ten times, the naked eye can see the middle window loading the smoothest.

The proper test data looks like this:

Continuous 24-hour pressure test results

• Ordinary proxy: average of 1 disconnection every 2 hours
• ipipgo: up to 18 hours of continuous operation without anomaly
• Failed request processing speed: ipipgo is 3 times faster than conventional solutions

Third, these pits must not be stepped on

I've seen people use the proxy manager as a faucet, thinking that by turning up the concurrency they can increase efficiency. In fact, this is no different from pouring water into a funnel, and you end up spilling it all out. The right way to do it is:

1. Protocol selection based on task type (http/https/socks5)
2. Set reasonable intervals between requests, don't let the server get out of breath
3. Regularly clean the failing ip, like ipipgo with auto-cleaning feature will save your mind!

IV. Practical selection guide

Picking an agent manager is like looking for a partner, it's useless to just look at the face value. You have to look at these three points:

1. Accuracy of heartbeat detection(ipipgo can find a failed node in 15 seconds)
2. Is the switching speed fast enough(Measured ipipgo switching time <0.3 seconds)
3. Logging detail(the path of each request can be traced)

QA time

Q: Why doesn't the program report errors after using ipipgo?
A: His proxy pool has intelligent routing that automatically bypasses congested routes, as if packing the data with a navigator

Q: What can I do about the fact that there are always a few requests that time out during peak hours?
A: In the backend of ipipgo putNumber of Spare ChannelsTuning to 3-5 is the equivalent of giving emergency lanes for data flow

Q: It works fine in testing, but falls off when you use it officially?
A: 80% of them are not openFlow Warm-upIf the server is not able to handle the sudden increase in requests, ipipgo has a progressive loading feature.

Finally, a word of caution: choose the proxy service providers do not just compare prices, like ipipgo such as with theAbnormal Traffic Fusing MechanismIt can save your life in critical moments. Next time you encounter a program that is stuck, check if it's time to upgrade your proxy manager first.
