[dorkbotpdx-blabber] VPN routers with ARM9 processors??

Fri, 01 May 2015 09:52:15 -0700

I have been experimenting with using dd-wrt to make a router that has OpenVPN capabilities. I have had success, and am seeing my precious 30Mbps bandwidth drop to 16Mbps in one case and to 7Mbps in another case. The CPU speed differences of the routers in each case exactly corresponded to the performance differences. I suppose I should be satisfied, but of course, I am not. Digging deeper, I found out that OpenVPN (or any VPN) requires a lot of floating point activity, and the Broadcom chips do not have this capability built into silicon. I am wondering if ARM processors in general and the ARM9 in particular have built in floating point? I have looked about, and can't find this info. If it does, there seems to be at least a few consumer-grade routers that have ARM9, like this one: http://www.arm.com/markets/enterprise/netgear-rangemax-next-wireless-n-router.php 

I think the Tomato project is working with ARM architecture...

Thanks... Jim W.
