“How fast is a proxy?” is one of the most-asked questions and one of the most misunderstood. The answer depends on which dimension of “fast” you care about — latency (round-trip time for one request) or throughput (how much data per second the connection sustains). Most users care about perceived speed, which is dominated by latency for interactive browsing and by both for video streaming. This cornerstone breaks down what actually determines proxy performance and how to diagnose slow sessions.
Latency vs throughput
Both are network performance metrics, but they measure different things:
Latency is the time for one round-trip — packet from your device to the destination and response back. Measured in milliseconds. Within a metro area, latency is 1-5ms. Cross-continent, 70-90ms. Halfway around the world, 250-350ms.
Throughput (also called bandwidth) is how much data the connection sustains per second. Measured in Mbps or Gbps. A “gigabit” plan typically measures 800-950 Mbps sustained after overhead.
For most interactive use — clicking around, reading pages, scrolling — latency dominates perceived speed. A 1 Gbps link with 300ms latency feels slower than a 10 Mbps link with 20ms latency. For video streaming, both matter: latency affects buffer refill responsiveness, throughput determines maximum sustainable video quality.
Proxies add latency (one extra hop) but rarely constrain throughput (edge server bandwidth is usually generous).
What the proxy hop actually costs
When you connect to a proxy, one round-trip becomes two:
- Without proxy: browser → destination, one hop.
- With proxy: browser → proxy, then proxy → destination, two hops chained.
The added latency is the round-trip to the proxy region. If you are in Berlin using a Frankfurt-region proxy, the extra hop is ~30ms. If you are in Jakarta using the same Frankfurt region, the extra hop is ~180ms — significant.
The reason region choice is the biggest lever for perceived speed: it directly controls the added latency. Picking a region close to you means the added hop costs 20-50ms, invisible to a user. Picking a region far from you means the added hop costs 200+ms, visible on every click.
Why region matters more than paper bandwidth
Provider marketing often emphasises server count or region count as if more is always better. What actually matters is:
Distance from you to the nearest region. Determines the added latency.
Bandwidth on the path between the region and your destination. Determines throughput ceiling.
Congestion on the region at your specific hour. Determines whether marketed bandwidth is available.
Six well-placed regions with excellent peering usually outperform sixty poorly-peered servers. AnyProxy’s six regions are chosen to be close to major user populations:
- Frankfurt (Europe, Middle East, Africa users near EU).
- Singapore (Southeast Asia, South Asia, East Asia).
- Virginia (North America eastern half).
- London (UK-specific, Pro).
- Tokyo (Japan, Korea, Pro).
- São Paulo (Brazil and neighbouring countries, Pro).
For most users, one of these six is within 100ms of round-trip latency — which means the proxy hop is barely perceptible.
How to diagnose a slow proxy session
If pages load slowly through the proxy, the debug order:
Step 1 — Check region latency in the picker. AnyProxy shows a live ms number per region. If your nearest region shows >150ms, you may be too far from any region. Try a different region.
Step 2 — Test the destination directly (if you can reach it from any network). If the destination itself is slow, the proxy is not the bottleneck.
Step 3 — Try a different browser tab or window. Extensions and background tabs consume bandwidth. Incognito mode disables most extensions.
Step 4 — Try from mobile hotspot. If proxy is fast on cellular but slow on your Wi-Fi, your Wi-Fi is the bottleneck.
Step 5 — Check whether it’s a bandwidth or latency issue. Bandwidth issue: video buffers, downloads slow, everything eventually loads. Latency issue: every click has visible delay, small pages load slowly, interactive apps feel sluggish.
Step 6 — If bandwidth-limited, consider Pro tier. Pro adds priority edge routing that shaves 20-40ms off large-file responses. Free tier is fine for text-heavy browsing; Pro helps for sustained video or heavy downloads.

Region choice by your location
Rough guide (typical latency in parentheses):
- Europe (Germany, France, UK, Italy, Spain, Netherlands): Frankfurt (~30-50ms), London (Pro, ~15-40ms in UK).
- Middle East (UAE, Saudi Arabia, Egypt, Turkey, Israel): Frankfurt (~80-110ms).
- Iran: Frankfurt (~110ms) closest.
- India: Singapore (~50ms), Frankfurt as backup (~140ms).
- Southeast Asia (Indonesia, Vietnam, Thailand, Malaysia, Philippines): Singapore (~30-60ms).
- China (mainland): Singapore (~78ms), Tokyo (Pro, ~65ms).
- Japan, South Korea, Taiwan: Tokyo (Pro, ~15-40ms).
- Australia, New Zealand: Singapore (~90-140ms), Tokyo (Pro, ~130-180ms).
- US East Coast: Virginia (~15-40ms).
- US West Coast: Virginia (~70-90ms), Tokyo (Pro, ~110-140ms).
- South America: São Paulo (Pro, ~15-50ms), Virginia (~100-140ms) as free-tier option.
- Africa (South Africa, Nigeria, Kenya, Egypt): Frankfurt (~80-140ms).
Pro tier’s three additional regions (London, Tokyo, São Paulo) matter most for users specifically near those locations. For everyone else, the free tier’s three regions are usually within acceptable latency.
What Pro tier’s priority routing actually does
The Pro upgrade includes “priority edge routing” that provides three specific improvements:
1. Reserved capacity on outbound bandwidth. Free tier shares bandwidth pools; Pro traffic has priority queueing so it doesn’t compete with free-tier traffic during peaks.
2. Higher-quality upstream peering. Pro traffic uses premium transit paths to destination CDNs, avoiding some longer routing hops.
3. Pro-only server capacity. Additional edge servers reserved for Pro users, so Pro sessions never wait behind free-tier queues.
The measurable effect: 20-40ms faster on large-file transfers, more consistent throughput during peak hours, fewer buffer refills on sustained streaming.
For 720p video or text browsing, free tier is genuinely fine. For 1080p sustained streaming, video calls (limited by WebRTC as covered elsewhere), or large-file transfers, Pro is worth the $4.99/month.
The bandwidth question — how much traffic can I push?
Free tier: no explicit bandwidth cap. In practice, sustained multi-GB downloads may hit soft rate limits during peak hours to protect free-tier capacity for other users. Casual browsing, YouTube, streaming — no visible cap.
Pro tier: no bandwidth cap. Sustained streaming and downloads run at the maximum the destination can serve.
Enterprise use (heavy scraping, automated tools) is outside the browser-proxy use case entirely — for that, a dedicated proxy SaaS product is the appropriate tool.
The one-page summary
Speed is dominated by region choice, not by proxy brand or tier. Pick the nearest region first. Free tier handles casual browsing and 720p video cleanly; Pro helps for 1080p video, sustained streaming, and heavy transfers.
If the proxy feels slow, switch region before doing anything else. Second, check whether it’s latency (every click slow) or bandwidth (large files slow). Third, test on mobile hotspot to rule out your Wi-Fi. Only after those three should Pro upgrade be the fix — most speed problems solve at step 1.
