Maximum Upload/Download Bandwith for VPN Client

Hello,

does anybody know if there is a maximum speed that the VPN Client can handle?

My Home Internet has 300/50 MBit/s but VPN Client seems to be capped at 100MBit/s. The Checkpoint Firewall itself has a 10GBit/s internet connection. This is not realy a problem at the moment but as bandwith needs are growing.....

 

Regards,

Jan

The question is: how are you testing it?

Sorry to not have mentioned it. I am using https://github.com/librespeed/speedtest 

This produces nearly 1GBit/s when connected to the local network. With VPN only 100MBit/s. With iperf3 I also get under 100MBit/s. So I thought about a hardcoded limit in VPN client.

Unless you're doing a test across multiple destination IPs, you're hitting a single processor core, which will naturally limit the amount of throughput.
I don't believe there is a hardcoded limit, but there may be an architectural limitation somewhere.
