HTTP Proxy Request Latency Optimization | Global CDN Acceleration Node Deployment

Why are HTTP proxy requests delayed?

When using proxy IPs on a daily basis, you often encounter slow loading web pages or lagging data transfers. The three main culprits that cause delays are:Network hops due to physical distance,Slow response caused by server overload,Additional Elapsed Time from Protocol Conversion. For example, if you use a U.S. proxy IP to access an Asian server, the data will have to go halfway around the world, and each routing node will add latency ranging from 10-50ms.

Four Steps to Proxy IP Latency Optimization

Step 1: Pinpoint the business scenario
First clarify your business type, live push streaming needs <50ms ultra-low latency, data collection can accept about 200ms latency. It is recommended to make a requirement comparison table:

Step 2: Intelligent Node Scheduling Technology
via ipipgo'sIntelligent Positioning APIThe system automatically matches the nearest service node. For example, if the target server is in Frankfurt, Germany, the system will automatically select the Amsterdam, Netherlands node (the physical distance is only 300 kilometers), compared to connecting directly from China, the latency is reduced by more than 80%.

Step 3: Protocol Stack Optimization Solution
The traditional HTTP/1.1 protocol establishes a connection for each request; instead, theHTTP/2 multiplexingIt can reduce the handshake delay of 60%. Turn on Protocol Optimization Mode in the ipipgo control panel and the system will automatically adapt the best transport protocol.

Step 4: Concurrent Connection Pool Management
set up5-10 continuous connectionsof multiplexed pools to avoid frequent creation of new connections. Measurements show that connection multiplexing can reduce the average request time from 320ms to 180ms, a reduction of 43%.

Global Acceleration Node Deployment Practice

ipipgo is in17 core hub nodes deployed globallyThe BGP Anycast technology is used to realize intelligent routing:

• Asia: Tokyo, Singapore, Mumbai nodes form a triangular network
• Europe: Frankfurt and London nodes for mutual disaster recovery
• Americas: Los Angeles and Miami nodes covering the east and west coasts

pass (a bill or inspection etc)Edge computing node preloadingtechnology, static resources in popular regions are cached in advance to the nearest proxy server. When user requests arrive, 90% static files can be obtained directly from edge nodes, reducing the number of trans-oceanic transmissions.

Frequently Asked Questions

Q: Why is there a big difference in proxy IP latency in the same region?
A: The quality of nodes varies from one service provider to another, and ipipgo uses theTier 1 Carrier Direct LineThe latency is reduced by 30-60ms compared to the normal service provider's line through multi-level forwarding.

Q: Which is more suitable for low latency scenarios, dynamic IP or static IP?
A: Dynamic residential IPs have a higher success rate when accessing websites with strict restrictions, and static IPs are suitable for scenarios where you need to maintain a long connection. It is recommended to turn on ipipgo backgroundhybrid model, the system will automatically switch according to the request type.

Q: How to test the real latency of proxy nodes?
A: Usecurl -o /dev/null -s -w 'time: %{time_total}s'command to test the real request elapsed time. ipipgo control panel built-inNode Latency Monitoring, real-time display of the response speed of each node.

Recommendations for technology selection

Focus on this when choosing an agency service provider:
1. Availability of self-constructed backbone network
2. Whether the refreshing mechanism of the dynamic IP pool is reasonable or not
3. Whether protocol-level optimized configuration is supported
ipipgo's.Intelligent Routing AlgorithmCan automatically avoid congested routes with itsPool of 90 million+ residential IP resourcesEnsure that each request can be assigned to the optimal node, through the actual test, compared with the ordinary proxy service can reduce the request delay of 40%-65%.
