This is amazing! Would you mind saying what kind of hardware you use for this? Ipredator used https://ipredator.se/guide/torserver to get to 101MB/s. So your setup should be even more extreme. Not within any definition of sane expenditure... The i7-4790k is Intel's highest clocked processor, ever. It's also Intel's current highest single thread performer. i7-4790k 4 x 4.0ghz cores = 1600 8mb 32gb ddr3-1600 88w $340 tsx-ni (1960 as OC'd by IPredator.) IPredator put a 10gbps nic in there and is moving only 800mbps OC'd (or 655mbps stock. Which is 165mbps/core, or 220mbps/core if isolcpus=1,2,3). Assume for moment this is cpu saturation. To do better you have to buy more core x ghz results like: i7-5930k 6 x 3.5ghz cores = 2100 15mb 64gb ddr4-2133 140w $580 So that's 1155mbps using all 6. Plus the more cache and much faster ram. And with good tor and os optimizations, you could probably hit 1250mbps. i7-5820k 6 x 3.3ghz cores = 1980 15mb 64gb ddr4-2133 140w $390 So that's 1090mbps plus. (ram for the above two: $420 32gb 4x8 ddr4-2133, non-OC) e5-2697v3 14 x 2.6ghz cores = 3640 35mb 768gb ddr4-2133 145w $2800 would fill 2000mbps plus. If you only need to fill 1000mbps, or however much bandwidth under that you're buying, just find the cheapest core x ghz that does that. While IPredator and their build may be cool, it fails to ROI, thus it's completely pointless to build. They wasted... https://www.google.com/finance?q=EURUSD Capital cost: - Water cooling to get 22.5% clock over stock. (More common/free OC gains are the low end of 5-18%.) You could simply pay $240 more for the i7-5930k and get more core x ghz performance than they did, without overclocking. (Overclocking is also by definition a risk to data/lifetime). Or pay $50 more and still get more. (Both assuming ram and other resources aren't used up due to two more core of tor instances). $1110 radiator (IPredator quoted $1570) $55 flow meter (IPredator qooted $50) $30 connectors, estimated qty 2 x $15 $100 coolant, qty 5 x $20 (IPredator quoted $120) $25 tubing coil $5 clamps, estimated qty 10 $95 waterblock $15 paste (IPredator quoted $25) wasted: $1435 low to $1920 high - Ram $1000 32gb 4x8 ddr3-2800, equivalent brand (IPredator quoted $1550) $280 32gb 4x8 ddr3-1600, non-OC wasted: $720 low to $1270 high - Case $730 5u case (IPredator quoted $660, saved $70) $300 1u case wasted: $360 low to $430 high - Motherboard $25 estimated economy vs. enthusiast savings wasted: $25 total capital wasted: $2540 low to $3645 high net performance gain vs. other capital options: zero or less $760 10G-PCIE2-8C2-2S (IPredator quoted $660, saved $100) $440 E10G42BTDA is it comparable? if so that's another $320 wasted (Total cost IPredator quoted: $5420) Ongoing rent cost: - 4u on the chassis (1u required + 4u wasted) - 3u on the radiator wasted: 7u Enthusias[m|t] is great, Tor could use some, and I've no want to diminish that... but back in the real world away from the show... if you just ran the i7-5930k stock in a barebones 1U, you'd have enough capital left to buy 2 more servers and enough rent to feed them at least some internet. (IPredator failed to quote in their review the amount of bandwidth purchased, the price/megabit, and thier cpu load at a given megabit. This makes it harder to fully analyze. Please post cpu load @ mbps data.) Moral: Operators... please don't waste your Tor budget on silly enthusiast crap. I'd also suggest testing FreeBSD. If you want to run real Tor contests, try for... - most bandwidth per node cost (depth, as above) - most usable nodes per cost (breadth) - etc And if you want me to win them, or this saved you $$$, donate here :-) btc 1BbEqMvEdsKiPuRT75HGrjZP8zqquamBPn ___ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays

Since people aren't going to like paying the 10g switchport fee, nor the price of small bandwidth over 1gbps on it, the fastest real world box for individual tor nodes is probably going to be that i7-5820k off a gig port for $1235 or less. ___ tor-relays mailing list tor-relays@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays

Re: [tor-relays] Help - My relay consensus has been stripped back to 20
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 This was reported yesterday 01.01.2015 in IRC too, for this relay: 3D7E274A87D9A89AF064C13D1EE4CA1F184F2600 The same it was pushing good amounts of traffic and the consensus weight dropped to 20 with no modifications made to the Tor config file or anything. You are the 3rd person who reports this, seams like worth investigating further. I can see both of them are exits, but doubt this has anything to do with it. Could it be a measurement problem from the bandwidth authorities? Why would it happen only to very few relays in this case?

Any of those in your log ? thanks BB Hi, Found the snippet with the changes for the guards: Tor Weekly News, 30th of July 2014 Once directory authorities have upgraded, they will “assign the Guard flag to the fastest 25% of the network”.

Re: [tor-relays] Reduced number of HSDir's
02.01.2015, 19:47 Kura: I think something must have happened, I restarted half a dozen or so of my relays over a week ago and none of them have been given the HSDir flag, which if I remember rightly is a 21 hour flag? I may be mistaken but, I would have expected that flag to be back with over a week of uptime. It used to be a 25 hour flag. 1 day plus an additional hour. I think (yes, that says I don't know) the period being longer than 24 hours had something to do with an attack to get relays under adversary control in the right position to become a HSDir for some hidden-services. If one pays for a relays by days an additional hour is an additional day for an attacker. I may have missed something, but maybe it was raised. I do remember that changes to Guards took place, like requiring them to have more bandwidth and to reducing the number of Guards clients would use. This was due to research.

Re: [tor-relays] Reduced number of HSDir's
