Network Conditions
Network Condition or Network Throttling

1. What's it?

Network Conditions (Network Throttling) v1 allows developers to simulate adverse networking environments. Proxyman provides various preset profiles:
Profile
Description
100% Lost connection
100 % lost all connection
Very Bad Network
Download/Upload: < 1mbps
Slow Network
Download/Upload: 5-10 mbps
Medium Network
Download/Upload: 10-20 mbps
2G (EDGE)
Download: <240kbps, Upload <200kbps
3G
Download: <780kbps, Upload <300kbps
4G (LTE)

Wi-Fi
Download: 25-40mbps, Upload 15-30mbps
Wi-Fi 802.11ac
Download: 150-250mbps, Upload 70-100mbps

2. Benefit?

  • Various preset profiles: 3G, 4G, Wifi, Bad/Medium Network, etc.
  • Help developers to simulate various network conditions (Download/Upload Bandwidth, Packets Dropped rate, delay).
  • Easier to test your app under a particular network condition.
  • Apply for system-Wide or certain domains.
Network Conditions v1 does not allow you to customize a profile. We will implement it in v2.
To better simulate the real-life, the download/upload bandwidth is not fixed, it might randomize in a given range.

3. How to use it?

You can access the feature by navigating to Tool -> Network Condition (CMD+SHIFT+J) or access from the right-menu context.
