Experiencing slow speeds with SoftEther VPN Client on Fedora 40

I need some help with an issue I’m facing using the SoftEther VPN client on my Fedora 40 machine. I’m experiencing significant slowdowns when accessing resources from my company through the VPN. Interestingly, this problem doesn’t occur when I’m using the same VPN client on my Windows machine.

I’ve already checked and confirmed that the MTU settings are the same on both systems.

Has anyone else experienced similar issues on Fedora or any other Linux distributions? Are there any specific configurations or tweaks that can help improve the performance?
