OpenVPN LZO Compression, heavy CPU usage?

    I'm just curious as what is suggested to use when it comes to LZO compression running on Tomato.

    Usually the CPU's in routers are not very powerful so I'm wondering if LZO will be a heavy CPU hitter or not?

    What are your experiences?

    I usually just set it to adaptive lzo compression and leave it be...

    There's two factors in play here... First, it depends on your router's processor... i.e. the CPU in old linksys WRT54G's were around 200MHz... A Netgear WNR3500L is 450MHz... Other routers are even faster...

    Second, it depends on the internet up/down speeds at each location. If your upload speed is only 1Mb or less then building a dedicated PC to run your OpenVPN server makes little sense.

    There is also a 'fast-io' command you can use for open-vpn which supposedly gives a little boost in performance.
