OpenVPN performance much better after reboot

[Carve7447]

Dear everyone,

I have noticed an issue that OpenVPN has sometimes a low performance for me (80 MBit/s from 250 MBit/s). After I do a reboot of Opensense, my performance is much higher (250 MBit/s from 250 MBit/s). I connect to the VPN via TCP.

Does anyone have an idea how I can find out what the reason is?

Best regards
