Re: [tor-relays] Nyx reported speed
I actually just logged into the one in my office to check on it. CPU is around 25%, RAM is ~30% free, 5111 connections. According to nyx, download is a pretty steady 500KB/s, to be expected with it limited at 500 with bursting to 600; and upload is fairly consistent around 350KB/s, a bit lower than expected, but perhaps due to this connection having some minor usage besides Tor might be the reason. (I think I'll try moving the cellular gateway to our main connection to see if that improves the upload on Tor.)
Perhaps the e1200 just can't handle the load like this Belkin can. It's sitting with CPU around 17%, RAM ~20% free, and ~2000 connections. But nyx is reporting very inconsistent speeds from 2KB/s to 600KB/s (though mostly topping out in the 20-40KB/s range) while I've been watching it this morning. The Tor server is a clone of the one in my office (Who knew these Barracuda's were actually useful for something?! lol) with the same hardware, software, and config, with the obvious exceptions of the IP addresses and names so I know the speed issue is probably not the server. And this is the one that is not sharing at all but only used for Tor.
(The routers are also configured the same, other than the hardware (different chipset and slightly slower CPU on the Linksys) and network differences. And the one in my office has the WiFi enabled while the other does not.)

I wondered if that might be the case. These are spare internet connections that we have for free, so we don't really want to put any resources into them as we don't actually use them. The one in my office we do have hooked up to a postal machine and cellular gateway and use for testing purposes, but the ones in our other buildings we don't use. I actually just upgraded the one in my office (curtesy of Goodwill for $4) from a v8 WRT54G (one of the crippled almost no RAM or ROM space) to the Belkin with 32MB of RAM which matches the Linksys e1200's RAM. I have both of them set for something like 32000 connections and I observed the one yesterday was sitting around 3000 connections with CPU and RAM resources still available. (I believe I read on DD-WRT's site somewhere that with 16MB of RAM it can support 32000 connections, though I've no first-hand experience with this, other than what I'm running now.)
If I get the chance to head to the other building where I have the other relay connected, I'll try connecting it directly to the internet and see how that affects the usage. (pf is set to not allow any connections besides ORport, DirPort, SSH, 80, and 443, so it should be fairly secure. Though I've not tested my rules to redirect 80 and 443 to DirPort and ORPort as my router was doing that for me.) On that note, if I plug directly in, I will also get an IPv6 address. Do I need to do anything besides set "IPv6Exit 1" to use it as an IPv6 exit? (Do I need to set the IPv6 OR port. It is not a static IP address and I don't know how often it will be forced to change.)

In our experience, most consumer routers don't support the 6000 simultaneous connections that Tor uses. I'd encourage you to try a different router, or an alternate connection, and see how that goes.
