What are the bandwidth limits for AWS Client VPNs.

Question

When connecting to an eu-west-2 AWS Client VPN with the AWS VPN Client we are seeing significantly reduced connection speeds compared to tests without the VPN connected.  
The [docs](https://docs.aws.amazon.com/vpn/latest/clientvpn-admin/troubleshooting.html#test-throughput) state there is a "10 Mbps bandwidth limit per user connection" but this does not match what we are experiencing (some users have around 100Mbps).

What bandwidth is supported by AWS for these services?  
Are there any approaches to improving performance?

Answer

I think the 1.25 Gbps bandwidth is for Site to Site VPNs per tunnel. I cant locate any documentation regarding the AWS VPN Client Limitations

Answer

hello,
 AWS Client VPN has a default bandwidth limit of 1.25 Gbps for each VPN connection. The 10 Mbps limit you mentioned might be a reference to the default bandwidth limit per user connection. AWS Client VPN allows you to define a maximum bandwidth limit for each user connection, and the default is 10 Mbps. However, this can be adjusted based on your requirements.

To check and adjust the bandwidth limit for a user connection, you can follow these steps:

1.Open the AWS Management Console.
    2.Navigate to the Amazon VPC console at https://console.aws.amazon.com/vpc/.
    3.In the navigation pane, choose "Client VPN Endpoints."
    4.Select your Client VPN endpoint.
    5.Choose the "Connections" tab.
    6.Select the user connection for which you want to adjust the bandwidth limit.
    7.Choose the "Details" tab.
    8.In the "User Connection Settings" section, adjust the "Maximum User Connection Bandwidth" as needed.

Keep in mind that other factors can contribute to reduced connection speeds, such as network latency, client device capabilities, and the underlying infrastructure. Here are some general tips for improving performance:
