[TriLUG] PoPToP VPN performance

[Ryan Wheaton]

Hey guys,

I've finally gotten my PoPToP VPN server to accept connections 
correctly, and all seems to be dandy, but it is unbelievably slow.  I 
couldn't get exact Mb/s times, but when I tried to copy the CentOS ISOs 
(about 1.8Gb) to a file share over the VPN, it was going to take about 
23 hours.  I have a cable modem at home, so i'd expect that performance 
would be considerably worse for dial-up users.  I expected it to be 
slower than physically being in the office, but not THAT much slower.  
Is this kind of performance expected?  Is there any way to tune the 
server to improve performance?

thanks,
