How to run OpenVPN in multiple threads?

Question

linux

Good afternoon.
The speed from hoster to my ISP in multiple streams is 90% of the bandwidth. And if in one stream - 10%.
OpenVPN works in one thread and shows low speed. Moreover, speedtest to the host server in several threads shows high speed, and in --single mode - just those 10%.
If it is impossible to do this with OpenVPN, then maybe Wireguard?
Thank you.
