5-6MB = megabytes per second? megabytes per hour? per year?
be more precise.

do not expect high performance with VPN and ESPECIALLY on this protocols.

no idea really how openvpn works, but if you can choose between TCP based 
and UDP based VPN then try both.

UDP is better in protocol point of view but it may be bad for OS overhead.

TCP is better with OS overhead but may result in retransmit mess when 
there are packet loss (both native traffic is retransmitted and then 
virtual traffic)
