Understanding Proxy Speed Metrics
What each metric means and what numbers to aim for.
Ping (ms)
TCP connection round-trip time. Measures how fast the proxy establishes a connection. Under 300ms is acceptable; under 100ms is excellent.
TTFB (ms)
Time to First Byte. The most critical metric for web scraping — it directly determines how fast pages load. Under 500ms is usable; under 200ms is ideal.
Speed (KB/s)
Download throughput. Matters for large-file downloads and multi-page scraping. Over 500 KB/s is good; under 100 KB/s is too slow for most tasks.
What Makes a Proxy Fast or Slow?
- 1Geographic distance — Proxies far from the target server add latency. Choose a proxy in the same region as your target.
- 2Server load — Shared proxies slow down under heavy use. Dedicated proxies are faster but cost more.
- 3Bandwidth allocation — Free proxies often have strict bandwidth caps. Premium proxies offer unlimited bandwidth.
- 4Protocol overhead — HTTPS and SOCKS5 add encryption overhead (5-15ms). HTTP is fastest but not secure.
- 5Target site response — Anti-bot systems add delays or CAPTCHAs, inflating TTFB.
| Endpoint | Purpose | User Scenario |
|---|---|---|
| httpbin.org | Neutral baseline | Pure proxy performance without anti-bot interference |
| google.com | Google infrastructure | SEO tracking, SERP scraping, Ads verification |
| cloudflare.com | CDN edge network | Bot detection, Cloudflare-protected sites |
| amazon.com | Proxy-hostile e-commerce | Price monitoring, review scraping, product research |
Frequently Asked Questions
Everything you need to know about proxy speed testing.
For web scraping, a TTFB under 500ms and a failure rate below 20% are generally acceptable. For high-volume scraping, aim for TTFB under 200ms. Our speed test runs 5 rounds against 4 real-world endpoints to give you a realistic picture.
Our test runs 5 rounds against 4 real-world endpoints (httpbin.org, google.com, cloudflare.com, amazon.com) and reports Min/Avg/Max for each metric. Results reflect real-world performance, but proxy speed can vary based on server load and network conditions.
Yes. Check the 'Authenticated proxy' box, enter your username and password, and select SOCKS5 as the protocol. The test will connect using your credentials.
Proxy speed varies due to server load, network routing, time of day, and target site response. Running 5 rounds and looking at the average gives a more stable result than a single test.
TTFB (Time to First Byte) measures the time from sending a request to receiving the first byte of response. It is the most important metric for web scraping because it directly impacts how fast you can fetch pages. Lower TTFB means faster scraping.
You can test up to 10 proxies at once in batch mode. Enable 'Batch mode', paste one proxy per line in the textarea, and click Test Speed. Results are displayed in a comparison table.
Amazon has aggressive anti-proxy detection that blocks known proxy IP ranges. Google is more permissive. If your proxy fails on Amazon but works on Google, it means the proxy IP is flagged by Amazon's security systems.
Yes, the Proxy Speed Test is 100% free with no signup required. You can test unlimited proxies. For production use with guaranteed uptime and sub-100ms latency, consider Rola IP's premium residential proxies.
