I'm a noob about this but I'll attempt an answer. If my logic is wrong please explain.
100 megabits per second is 12.5 megabytes per second<https://www.google.com/search?q=100+megabits+per+second+in+megabytes+per+second>so that would be our goal: 12.5 megabytes per second I'm using tinc <http://www.tinc-vpn.org/> and it defaults to blowfish for it's cipher. Running `openssl speed blowfish` gives me: > The 'numbers' are in 1000s of bytes per second processed. > type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes > blowfish cbc 9937.00k 10879.68k 10941.02k 11050.11k 10896.43k So, benchmarks at about 10 megabytes per second but there is going to be overhead needed for other stuff. My unreliable guess is I can handle about 5-6 megabytes per second of VPN traffic. Half of what you want. That is on my Netgear WNDR3800<http://wiki.openwrt.org/toh/netgear/wndr3800>which runs an Atheros AR7161 rev 2 at 680 MHz. Those TP-Links you mentioned run (newer?) chips at a slower clock. I have no idea how that will compare. But: Comparing other ciphers on the OpenSSL benchmark<http://wiki.openwrt.org/inbox/benchmark.openssl>page it looks like those TP-Links are about 2/3 or as fast as my WNDR3800. Going by the benchmark page the TP-Link TL-WDR4900<http://wiki.openwrt.org/toh/tp-link/tl-wdr4900> ($170<http://www.amazon.com/TL-WDR4900-Ultimate-Wireless-Gigabit-Router/dp/B00A0VCJ3K/ref=sr_1_3?tag=wamjr-20&ie=UTF8&qid=1384041044&sr=8-3&keywords=TL-WDR4900>) looks like it has some crypto hardware acceleration and it might get you there.
