Slow conection with server

Christopher

Good morning/day/evening everybody!
I need your help.
Company where im working have a 3 bilding in city, and they worked on windows VPN, but when users work with server, they use OpenVPN connetions.
Problem here: connection very slow. Veeeeery slow and crash sometimes.
I want change UDP connction on TCP. But i cant find where i need to do it. And, after i will change configuration, need to reboot the server?

Thanks
