Concurrent connection threads refer to how many separate connections a proxy can handle at the same time — think of them like lanes on a highway. The more threads available, the more “lanes” there are for traffic (requests) to pass through without slowing down.
Example:
If your proxy plan allows 100 threads, it can handle up to 100 simultaneous connections. This might include:
- Multiple browser tabs open at once
- Several tools using the proxy
- Different users connected to the same proxy
Key Things to Know
- Exceeding the thread limit can cause dropped or failed connections.
- Threads ≠ speed — upgrading your internet speed will not change your thread allowance.
- Websites with heavy content or multiple tabs can consume more threads than expected.
What To Do If You Hit the Limit
If you’re experiencing connection issues related to thread limits:
- Try reducing the number of open tabs or simultaneous tools.
- Monitor your usage against your current thread limit.
- Remember that browsers and applications may open several connections in the background.
Rotating Residential Proxies
Self-managed Rotating Residential Proxies have a limit of 100 concurrent connections and a speed limit of 100 Mbps.
There is no Upgrade option for this proxy type, and there are no plans to increase these limits at the moment. Rotating Residential exit nodes can vary in capacity, so higher connection and speed limits are not currently available.
If you reach the limit, reduce the number of simultaneous connections before trying again.
For other proxy types, available connection limits depend on the product and network. Check your dashboard to see whether a Change option is available.
