Most proxy providers quote "unlimited bandwidth" and "99.9% uptime" but never tell you what happens when you actually push their connections hard. We wanted real numbers: how many concurrent requests can a single sticky proxy IP handle before it breaks?
We tested Jio and Airtel sticky proxies with an Instagram-style workload — HTML pages, JSON APIs, JPEG images, 64KB binary blobs, and slow-responding servers — ramping from 5 to 50 concurrent connections. Here's what we found.
The Test
We ran a 90-second sustained load test at each concurrency level (5, 10, 15, 20, 30, 40, 50) through a single sticky proxy per carrier. The workload mimics real scraping operations:
- HTML pages (~50KB) — like Instagram profile pages
- JSON APIs (~5KB) — like API endpoints
- JPEG images (~25KB) — like profile pictures
- Binary data (~64KB) — like media payloads
- Slow servers (5s response) — like rate-limited endpoints
- IP verification — confirming the proxy returns the same IP every time
Every request went through the same sticky proxy IP. No rotation. No fallback. Same IP, same device, same cell tower. This is the real-world scenario for sticky proxy users.
Results at a Glance
| Concurrency | Jio Success | Jio Avg Latency | Airtel Success | Airtel Avg Latency |
|---|---|---|---|---|
| 5 | 98.7% | 3.1s | 100.0% | 3.9s |
| 10 | 100.0% | 3.2s | 99.2% | 3.7s |
| 15 | 98.7% | 3.3s | 97.8% | 3.6s |
| 20 | 98.2% | 3.0s | 98.3% | 3.6s |
| 30 | 98.8% | 3.2s | 99.4% | 3.8s |
| 40 | 98.6% | 3.4s | 98.3% | 3.4s |
| 50 | 39.5% | 3.6s | 96.7% | 4.0s |
The cliff at 50 concurrent is dramatic for Jio — success drops from 98.6% to 39.5%. Airtel stays above 96% even at 50 concurrent.
What Happens at Jio's Breaking Point
At 50 concurrent connections through Jio, something interesting happens. The first 3 batches succeed fine. Then the 4th through 12th batches all return zero successes — every single request gets rejected with SOCKS5 error code 0x02 (connection not allowed by ruleset).
This isn't a gradual degradation. It's a cliff. The Jio radio connection appears to briefly destabilize under the sustained burst, causing the proxy to reject all incoming connections for approximately 30-40 seconds. Then it recovers, and the last 3 batches succeed again.
This pattern is critical for anyone running automated scraping: if your Jio sticky proxy hits 50+ concurrent requests, expect 30-40 second windows of total failure, not gradual slowdown.
Airtel's Resilience Under Pressure
Airtel tells a different story. At 50 concurrent connections, the worst single batch was 47/50 (94% success). No total failures. No cliff. No blackout windows.
The latency does increase — from 3.9s at 5 concurrent to 4.0s at 50 concurrent — but the increase is marginal. Airtel's network absorbs the load by distributing it across its radio infrastructure rather than buckling under burst pressure.
For scraping operations that need reliability above everything, Airtel is the clear winner at high concurrency.
Latency Comparison
| Concurrency | Jio Latency | Airtel Latency | Difference |
|---|---|---|---|
| 5 | 3.1s | 3.9s | Airtel 26% slower |
| 10 | 3.2s | 3.7s | Airtel 16% slower |
| 15 | 3.3s | 3.6s | Airtel 9% slower |
| 20 | 3.0s | 3.6s | Airtel 20% slower |
| 30 | 3.2s | 3.8s | Airtel 19% slower |
| 40 | 3.4s | 3.4s | Equal |
| 50 | 3.6s | 4.0s | Airtel 11% slower |
Jio is consistently faster at lower concurrency levels. But at 40+ concurrent, the gap narrows to near-zero. Airtel's latency stays stable regardless of load; Jio's latency starts climbing as it approaches capacity.
Data Throughput
| Concurrency | Jio Throughput | Airtel Throughput |
|---|---|---|
| 5 | 7 KB/s | 5 KB/s |
| 10 | 6 KB/s | 5 KB/s |
| 15 | 4 KB/s | 4 KB/s |
| 20 | 5 KB/s | 4 KB/s |
| 30 | 5 KB/s | 5 KB/s |
| 40 | 5 KB/s | 5 KB/s |
| 50 | 2 KB/s | 4 KB/s |
At 50 concurrent, Jio's throughput drops to 2 KB/s because of the failure windows. Airtel maintains 4 KB/s even at maximum load.
IP Consistency: The Sticky Proxy Promise
Throughout all tests, both carriers returned exactly 1 unique IP address. That's the entire point of sticky proxies — no matter how many concurrent connections you open, they all come from the same IP.
This matters because many target sites (Instagram, LinkedIn, Amazon) flag requests that come from multiple IPs in short succession. With a sticky proxy, every request — whether you're running 5 or 50 concurrent — appears to come from the same device on the same network.
The Sweet Spot: 30 Concurrent
For production scraping workloads, 30 concurrent connections is the sweet spot for both carriers:
- Jio at 30: 98.8% success, 3.2s average latency
- Airtel at 30: 99.4% success, 3.8s average latency
Both carriers deliver near-perfect reliability at 30 concurrent. This gives you enough headroom for most scraping operations while staying well below the failure threshold.
If you're running more than 30 concurrent connections through a single sticky proxy, you should distribute across multiple proxy IPs instead of pushing one IP harder.
Why These Numbers Matter
Most proxy comparison articles test with 1-5 concurrent connections and declare a winner based on latency differences measured in milliseconds. That's not how real scraping works.
Real scraping workloads look like this:
- An Instagram profile scraper hitting 20 endpoints per profile
- A price monitoring tool checking 30 product pages simultaneously
- A data pipeline processing 50 URLs in parallel batches
At 5 concurrent, both carriers are perfect. The difference only shows when you push harder. And the difference between "gradual slowdown" (Airtel) and "total blackout for 30 seconds" (Jio at 50+) is the difference between a retry succeeding and your entire scraping pipeline stalling.
Recommendations by Use Case
For Account Management (5-10 concurrent)
Either carrier. Both deliver 99%+ success. Jio is slightly faster (3.1s vs 3.9s).
For Moderate Scraping (15-30 concurrent)
Either carrier. Both deliver 98%+ success. Airtel has slightly better consistency.
For Heavy Scraping (30-40 concurrent)
Airtel preferred. Both work, but Airtel handles 40+ better. Jio starts approaching its ceiling.
For Maximum Throughput (40-50+ concurrent)
Airtel only. Jio has catastrophic failure windows at 50. Airtel stays above 96%.
For Lowest Latency (speed-critical)
Jio at low concurrency. Jio is 15-25% faster at 5-20 concurrent. At 40+, they're equivalent.
The Bottom Line
A single sticky proxy from either carrier can handle far more concurrent connections than most people assume. 30 concurrent connections with 98%+ success is production-ready for both Jio and Airtel.
If you need to push beyond 30, Airtel is the safer choice. Jio works fine up to 40 but catastrophically fails at 50. Airtel maintains composure throughout.
The real takeaway: stop thinking about proxies in terms of "which is faster" and start thinking about "which handles my actual workload." At low concurrency, either works. At high concurrency, Airtel is more resilient. And if you're hitting 50+ concurrent on a single IP, you should probably be using multiple proxy IPs instead.
FAQ
How many concurrent connections can a sticky proxy handle? Airtel handles 50+ with 96.7% success. Jio handles 40 with 98.6% success. Both are solid at 30 concurrent (98%+ success). If you need more than 30, Airtel is more resilient under pressure.
Why does Jio fail at 50 concurrent connections? Jio's radio connection briefly destabilizes under extreme burst load, causing a 30-40 second window where all connections get rejected. Airtel absorbs the same load without total failure.
What is a sticky proxy? A sticky proxy gives you the same IP for every request. Unlike rotating proxies, sticky proxies are essential for logged-in sessions, account management, and any scraping that requires IP consistency.
Is Airtel or Jio better for web scraping? For moderate workloads (up to 30 concurrent), both are excellent. For high-concurrency scraping (40-50+), Airtel is significantly more stable. For the highest per-request success rate at lower concurrency, Jio has a slight edge.
Should I use multiple proxy IPs instead of pushing one hard? Yes. If you need more than 30 concurrent connections, distribute across multiple sticky proxy IPs. This gives you better reliability than pushing a single IP to its limits, regardless of carrier.
