Performance Impact of Split Tunneling with WireGuard
Split tunneling with WireGuard can impact performance, as it involves additional processing and routing overhead. The performance impact depends on several factors, including:
Network configuration
The performance impact can vary depending on the network configuration, such as the number of devices connected to the VPN, the bandwidth available, and the latency between the devices.
Traffic patterns
The performance impact can also be affected by the traffic patterns, such as the size and frequency of the packets being transmitted.In general, split tunneling with WireGuard can introduce a small amount of latency, as the traffic needs to be inspected and routed differently.
However, the impact is typically minimal and should not be noticeable for most users.To compare the performance with and without split tunneling enabled, you can run speed tests and measure the latency. You can use tools like iperf or speedtest-cli to measure the bandwidth and latency.Here
is an example of how to measure the performance impact of split tunneling with WireGuard:
- Enable split tunneling on your WireGuard client.
- Run a speed test to measure the bandwidth and latency.
- Disable split tunneling on your WireGuard client.
- Run a speed test again to measure the bandwidth and latency.
By comparing the results of the two speed tests, you can see the performance impact of split tunneling.
