why pptpd is way slower than openvpn ?

Hi,

I have a server with 100Mbs up and down, so it's fast enough, it's running archlinux, and I have installed and configured both pptpd and openvpn, and they both up and running.

but when I connect through PPTP and try to download something (to max out the connection) I get poor speed, around 200-300Kb/s

in the other hand, when I connect through OpenVPN and try to download the same thing, I almost max my speed at 2Mb/s

any ideas why this happens ?

here's my /etc/pptpd.conf

# Read man pptpd.conf, see samples in /usr/share/doc/pptpd
# and write your pptpd configuration here

# TAG: option
#       Specifies the location of the PPP options file.
#       By default PPP looks in '/etc/ppp/options'
#
option /etc/ppp/options.pptpd

# log connections
logwtmp

# ip ranges for local and remote
localip 192.168.1.2
remoteip 192.168.1.234-238,192.168.1.245

and here's my /etc/ppp/options.pptpd

# The name of the local system for authentication purposes
name pptpd
