My VPN between our two offices are extremely slow. Both offices have 5 Mbit/s Internet connection and a Cisco Pix 501. My measurements show that trafic to Internet is actually 4-5 Mbit/s at both places, but trafic between our offices not nearly that good, I only get 0.2 to 0,3 Mbit/s.
While loaded links are certainly one possibility to consider, I believe that there may be other possibilities to consider. Whenever I hear someone describe performance difficulties in VPN I wonder about fragmentation. If the end stations are creating large frame sizes and the VPN adds extra headers, it is likely to produce frames that need to be fragmented. The overehad of doing the fragmentation and reassembly on the devices that are carrying the VPN traffic can have negative impact on VPN performance. If Jocke can set the max frame size lower on a pair of end stations and then test performance between that pair I wonder if performance would improve?
