vpn speed loss

[Beni Brinckman]

Hi,

I'm running FreeBSD 9.0-RELEASE (pc-bsd 9.0 actuallly) on amd64 and
I'm using a vpn connexion.
My problem is the enormous speed loss i'm having when I'm using the
vpn connexion.
I have tried Openvpn and mpd5 (with a pptp and l2pt connexion) and the
max speed (according to various speedtests) is 5 to 6MB.
Without the vpn I'm having 45-50 MB... My vpn service has servers in
several European countries and US, Canada, etc. The speed stays the
same.
So I don't  think it is a specific bsd problem but the lines/connexion
between ISP's.
Is this the "normal" speed when using a vpn (independently of the used
program to connect) ? Because from 45-50 back to 5-6 is a big step
backward...
Thanks for any insights here.
