Proxy Speed and Success Rate Claims Compared (2026)

What proxy speed and success rate claims do providers make?

Five providers publish a success rate, and the gap between the highest and the lowest is just 0.55 percentage points.

All figures are as advertised by each provider on its own page, checked on October 28, 2026. Nobody here measured them.

As advertised, checked on October 28, 2026. Oxylabs also lists 0.6 s on the same page.

Success claims barely differ. Response claims differ by almost three times.

Why won’t you see the advertised numbers?

An advertised success rate is an average across every customer and every target, and your scraper is neither.

• Your targets are harder: A shop with strong bot protection blocks far more requests than an average site. The success rate drops when the target fights back, whatever the pool.
• Targeting narrows the pool: City or ZIP targeting picks from a smaller set of IPs than country targeting, so fewer good addresses are available for each request.
• Distance adds latency: Response time includes the trip from your server to the proxy and on to the target. A server far from both adds time to every request.
• Sessions change the maths: Sticky sessions keep one IP for minutes or days. If that IP slows down or gets flagged, every request in the session feels it.
• Definitions aren’t published: None of the pages read says what counts as a success, which target was used, or over what period the average was taken.

Server location is the one you control most easily. If you run scrapers on rented machines, our ranking of VPS for proxy servers lists locations worth comparing.

Which claims are hard to compare?

Two pages in this table give two different numbers for the same kind of thing.

• Oxylabs lists an average response of 0.6 s in its plan features and 0.41 s in its IP quality section, with no note on why they differ.
• Proxy-Seller cites 99.5% success in its text and 99.7% uptime in its page description. Uptime and success rate measure different things.
• DataImpulse describes its roughly 1 s response as 2x faster than average, without saying which average.
• Bright Data’s residential pricing page gives no success or response figure; its 99.99% uptime belongs to the Enterprise plan’s SLA.

Compare like with like: success with success, uptime with uptime.

How do you test a proxy’s speed and success rate yourself?

Fifty requests to your real target tell you more than any homepage number.

1. Pick your real targetUse a page you actually need to scrape, not a test site. Success on an easy page says little about a protected one.
2. Match your settingsUse the same country or city targeting and the same rotating or sticky session type you’ll run in production.
3. Send 50 requestsRun the script below with your proxy details. It counts answers with a 200 status and times each successful request.
4. Read the medianUse the median response time, not the average, so one slow request doesn’t skew the result.
5. Repeat at a busy hourRun the same test at the time of day you’ll scrape most, then compare the two runs before you decide.

import statistics
import time

import requests

PROXY = "http://PROXY_USER:PROXY_PASS@PROXY_HOST:PROXY_PORT"
URL = "https://httpbin.org/ip"
RUNS = 50

proxies = {"http": PROXY, "https": PROXY}
times, ok = [], 0
for _ in range(RUNS):
    start = time.perf_counter()
    try:
        r = requests.get(URL, proxies=proxies, timeout=15)
        if r.status_code == 200:
            ok += 1
            times.append(time.perf_counter() - start)
    except requests.RequestException:
        pass

print(f"success: {ok}/{RUNS} ({ok / RUNS:.0%})")
if times:
    print(f"median response: {statistics.median(times):.2f} s")

Swap URL for your own target before you trust the result. Want a quick live check first? You can test your proxies with GoToProxy, or try a few addresses from our free proxy list to learn the script before you spend paid traffic.

What if a proxy doesn’t match its claims?

You don’t have to commit to a big plan to find out, because most of these providers let you start small or ask for money back.

Terms as listed on each provider’s residential page on October 28, 2026. Read the full refund policy before you pay.

The calm way to buy is to run the 50-request test inside the window. Decodo gives you 14 days on eligible subscriptions, DataImpulse 7 days, and Proxy-Seller only 24 hours, so test Proxy-Seller on the day you buy. No plan in this table needs a long contract to start.

Our residential proxy prices report lists what each of these trials and small buys costs per GB.

What can’t advertised figures tell you?

Every figure here is a provider’s description of itself on one day, not a measurement.

• How the numbers were measured: target sites, test period and the definition of success aren’t published.
• How your targets will respond: protected sites block more, whatever the pool size.
• Whether figures still hold after October 28, 2026.
• Performance by country or city, which none of the pages break down.
• Speed through your own tools, such as a headless browser. See Playwright vs Selenium for how each handles proxies.
