Network performance problems with VPN connections
Network performance problems with VPN connections
It seems like the connection quality through the VPN is significantly impacted. The speeds you're experiencing—around 10 mbit/s instead of the expected 300 mbit—could stem from several factors. It might be related to how the VPN handles traffic, possibly introducing additional overhead or congestion. The firewall aspect of the VPN appliance could also play a role, especially if it's managing multiple data streams. Additionally, network routing and local infrastructure at either end might be contributing to the issue. Investigating the VPN configuration and traffic patterns would help clarify the problem.
It's an IPsec or OpenVPN connection. Both ends use modern hardware with strong crypto support like AES-NI on Intel chips. You can achieve comparable speeds to non-VPN connections without the tunnel. Route control via BGP is possible but may vary between setups.
It could be your connection speed is too high or it's verifying packet delivery (TCP). Would you like to try UDP instead and check the communication between the two sites?
