Unfortunately, that's not really much help. First of all, clock
rates are a really poor way to compare CPUs of different
architectures. More importantly, a lot of VPN appliances use ASICs
that off-load the crypto from the CPU. The WRT54G has no such
accelerator. So you're comparing apples to orange juice. :)

Now that's interesting. I'll have to give the 3rd party firmware a
try. I haven't bothered with my WRT54G because I haven't percieved a
need yet. Sounds like I would get some benefit after all. I wonder
what the differences are to cause such a result.
