The CPU usage is approx 15-20% on both of them when copying the 200MB 
ISO image thru the tunnel. Speed is about 280kB/s.
But when I connect using PPTP to each single node and upload/download 
from/to my desktop to/from respective PC the speed is about 1MB/s 
(outside the rush hours).
It seems like network problem somewhere between their 2 sites or some 
bad configuration.
