Understanding Proxy Speed
What affects proxy speed?
Proxy speed depends on several factors: the physical distance between you and the proxy server, the proxy provider's network infrastructure, the number of concurrent users sharing the same proxy, and the proxy type. Dedicated mobile 4G proxies typically have lower latency than overloaded shared datacenter proxies because they use real cellular connections with dedicated bandwidth. Network congestion, time of day, and the target website's response time also play a role.
How to interpret latency results
Latency under 200ms is excellent and suitable for real-time tasks like social media automation, sneaker bots, and ad verification. Latency between 200-500ms is good for most use cases including web scraping and SEO monitoring. Between 500-1000ms is fair — adequate for bulk data collection but may cause timeouts on strict websites. Above 1000ms indicates a slow proxy that may struggle with time-sensitive operations. Always test during your actual usage hours for accurate results.
Mobile 4G vs datacenter speed comparison
Datacenter proxies often advertise sub-50ms latency, but this is misleading — they frequently get blocked, requiring retries that negate any speed advantage. Mobile 4G proxies from Proxy Poland typically show 150-400ms latency on Polish Orange LTE, but achieve near-100% success rates on major platforms. The effective throughput (successful requests per minute) of a mobile proxy is usually higher than a datacenter proxy that gets blocked every few requests. For sustained operations, reliability matters more than raw speed.
Tips for optimal proxy performance
Choose proxy servers geographically close to your target websites. Use HTTP protocol instead of SOCKS5 when possible — it has lower overhead. Keep connections alive with HTTP keep-alive headers to avoid reconnection costs. Schedule bandwidth-heavy tasks during off-peak hours (2-6 AM local time). Rotate IPs only when necessary — each rotation adds 2-3 seconds of delay. For maximum speed with Proxy Poland proxies, connect from a European server to minimize the hop distance to our Warsaw-based modems.
