Someone just got 149.08 MB/s on a non-exit relay. 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...

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
