Advanced Throttle
Get more granular control over your network environment with 10+ professional network profiles. Advanced Throttle allows Emuluxe Pro users to test for specific world-wide mobile conditions.
Network Profiles
We provide a curated list of profiles based on common mobile standards and real-world carrier data from OpenSignal.
| Profile | Download | Upload | Latency (RTT) | Use Case |
|---|---|---|---|---|
| 4G / LTE | 30 Mbps | 15 Mbps | 40 ms | Modern high-speed mobile networks. |
| Fast 3G | 1.5 Mbps | 750 Kbps | 100 ms | Reliable mobile data in urban areas. |
| Slow 3G | 780 Kbps | 330 Kbps | 300 ms | Standard "on-the-go" mobile data. |
| Edge / 2G | 240 Kbps | 200 Kbps | 600 ms | Rural or indoor signal with high latency. |
| Offline | 0 Kbps | 0 Kbps | 0 ms | Testing Service Workers and offline UI. |
| Custom | User Defined | User Defined | User Defined | Enterprise-only custom bandwidth limits. |
Technical Implementation
Beyond simple download/upload caps, Emuluxe's Advanced Throttle simulates the Packet Jitter and Throughput Variance found in modern wireless stacks.
We utilize the Network.emulateNetworkConditions command in the Chrome DevTools Protocol (CDP). Unlike Basic Throttle (which only limits bandwidth), Advanced Throttle allows us to specify:
- Offline: Boolean flag to completely sever the connection.
- Latency: Artificial delay in milliseconds (RTT).
- DownloadThroughput: Max download bytes per second.
- UploadThroughput: Max upload bytes per second.
Best Practices
To ensure your application is resilient, we recommend testing following scenarios:
- The "Lie-fi" State: Use Slow 3G to see how your app handles the transition from "Active" to "Offline" before the UI realizes the connection is lost.
- Bundle Splitting: Check if your main
index.jsbundle takes more than 10 seconds to load on Edge connections. If so, consider more aggressive code splitting. - Optimistic UI Updates: Verify that your UI updates immediately on actions (like "Like" or "Save") and gracefully rolls back if the request fails on a high-latency connection.
[!TIP] Use the Emuluxe Extension to apply network throttling at the kernel level for even more realistic simulation that affects all tabs in your browser instance.
