Speed. I want bloody speed. VPN

    OK Folks, I got the VPN working.... very slowly. I canged it from 3DES to DES and it was faster.
    I can download a certain web page over the Cable in 2 seconds. Over the VPN it takes about 21 seconds. So I think that is a good suggestion of the penalty for using the VPN.
    There was no measurable difference between hardwire to the VPN router and wireless connection to the VPN router. That was sort of expected.
    Does the SHA Authentication setting matter any?
    Are there any other suggestions for settings that would effect speed of the VPN (or encryption)?
    Now since this is a Gateway to Gateway VPN, all encryption is done by the VR042 router chip. Are there routers with faster chips? If I made the VPN between the XP client and the VR042, I would expect no change in speed as the one router would still be the limiter, but if the VPN was between an XP client and a WIN 2003 machine, would they be able to up their encryption rate so that the VPN was noticably faster?
    Any other suggestions on this... papers or previous posts that would address this?
    How long before the planet Mercury crashes into the sun?
    Enquiring minds want to know.
    Thanks much, Mike Breeden - Director of Office Physical Agro hydrology

    There are routers with faster CPUs...the rv082 and rv016 have 533MHz CPUs..vs the 266 for the 042.

    However...I doubt that's your issue on a single PC single VPN.

    Is netbios traffic enabled in the tunnel? That can eat up a good percentage of the bandwidth.

    Sounds like your upload speed could be the limiting factor. Why don't you do away with the VPN tunnel and go for a wireless bridge? That way you would have much better speed and at the same time could get rid of one Internet connection and save money on top.
