I have 5 dual xeon E5-2690 (2x 20MB so 40MB cache total) running Ubuntu and wanted to give mining a shot. (have free electricity)
I tried monero and get close to 1,000h/s from each server running 20 threads each for a total of 5,000h/s from all servers. Is that good?
Tried xmrig and stak-cpu with same results (large pages enabled)
Am i better off mining a different coin like zcash or Aeon?

Thank you for any suggestions

You can check different CPU-coins. Look at ZOIN, VRM, XMG. Maybe they can be more profitable. Anyway 10 CPUs 2690 with "free" Wink

electricity are good setup.

youc an try to mine verium or zoin, they are good for cpu coin, or also magi, but they don't have the marketcap of monero and some of them could probably be died in few months if not yet

I think your best option would be to continue in XMR after all you got a very good mining power considering that CPU's are a little old

I tried mining XMR with an i7 3630QM and reached close to 80h / s with the 8 nucles

Laptops don't exactly have great cooling and your particular model of CPU isn't the most efficient either. Xeons and Opterons actually.mine pretty well for the price (you can find Opterons for sub $30 used but mobos are a little more), and so that's why most people don't buy more modern CPUs just for mining.

You could also mine Verium.

Here is a hashrate comparison spreadsheet:
https://docs.google.com/spreadsheets/d/1O-hyFS-bqsopttmql6NgYWlWej9rZk_lm5MWivnehXg/edit#gid=0

Your dual xeon Machines should be quite good at Verium mining.

That looks about right. i7z helps you visualise if the 'correct' cores are unloaded. You don't need to split into two processes - affining the process to the cores works fine.

I get ~630h/s from one node of 2 e5-2650l v1s. Not very power efficient, but with rising prices....

so you are saying since I have 2 numa nodes to run two separate instances of the miner?

lscpu output shows:
NUMA node0 CPU(s): 0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30
NUMA node1 CPU(s): 1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31

Since it's 20MB cache per cpu, you would do 0,2,4,6,8,10,12,14,16,18 for instance #1 and 1,3,5,7,9,11,13,15,17,19 for instance #2 and leave the rest of the cores unused?

Thank you

does anything know if my layout is correct?

Thank you for your help

my 2cents but if your planning to mine xmr a single vega pulls 1500-2000 hs cryptonight algo, so with the network difficulty i'd join the gravy train and utilize those pci x lanes

Monero is for GFX now

Wow. That took you so much cognition. No, it's not, if you have hardware sitting otherwise 'idle'. Besides, if you have a GPU, you're better off mining pretty much any other coin (above SM_3.0 capable cards only - Cryptonight is still worthwhile on older cards - 770s, etc)

9 kH/s gets me 0.0033 BTC / day payout on Nicehash which is not insignificant. Make sure you arrange your cores correctly to use the cache for each CPU package - Linux arranges them as (4 cores, 8 threads)
Package 1 | Package 2
0 1 2 3 | 4 5 6 7 (HT1)
8 9 10 11 | 12 13 14 15 (HT2)

So as an example if you need 6 threads per CPU package to fill your cache, fill all of one HT set on both package, then fill it out with additional HT cores.

That would be affinity set to (Package 1) 0,1,2,3, (Package 2) 4,5,6,7, (Package 1) 8,9, (Package 2) 12,13

If you are only mining with the box, you get better heat efficiency by turning off cores in the BIOS + using larger threads (above assumes xmr-stak-cpu)

Cheers!
