I have actually always wanted to ask this question. It is somewhat off-topic but to a degree still related. Why is it that Bitcoin mining is now difficult to proceed to with a regular desktop computer? Most around this forum have made a point every time to mention that desktop computers cannot support Bitcoin mining software.

Thanks!
It seems that ZR5 on v3.1.9 AES-NI compile is a little faster than v3.1.7 (about 5 khash)
But decred is just SSE2 on both Intel and AMD - almost same speed per thread on Intel i7 and Phenom II x4 940?
Strange thing is that both of them don't succeed to submit a share for about 5 minutes. (Maybe the network diff is too high now).

Nice work, nice bump, went from 890kh/s on this one rig to 940kh/s over 3.1.5 I was using on it.
Intel Duel CPU 21 cores used on EVGA SR2 MB.

W7 64bit w/ VB Linux
Not sure how that happened, I didn't touch x11. There is no change for me.
Maybe you had fewer processes running.
My AMD rig is seeing a small loss 2291 v3.07 down to 2243 v3.1.8
48 cores full Linux 64bit also x11
If this is a NO_AES_NI compile then, yes there were improvements to many algos.

I used the following:

which gets 373-375 khash on that Phenom II.
P.S. Stall searching my Ubuntu image for cross-compile.
If I don't find it I will use MSYS and Win 7 x64...

The SSE2 compile should be on par with scmorse.
Perhaps I should change the recommendation to always use -march=core2 for all non-aesni cpus since it works
on AMD as well.

Add "-DNO_AES_NI" to the CFLAGS.
I haven't gotten Windows to compile since I forked from TPruvot, the project file hasn't been maintained.
Good luck.

Very nice bump in hashrate for ZR5! 
v3.1.7 - goes to 830-840 khash
v3.1.8 - goes to 825-830 khash
Read something about SSE2 optimisations on some algos - does that means that I can use your miner in AMD cpus that have SSE2 (since they lack AES-NI support)?
P.S. You are very welcome for the scmorse's tip.
Right now I'm making your miner default for my i7 cpu.

The new version 3.1.6 returns only invalid (low-diff) shares with zr5 algo on ziftrpool.io
AKAIK v3.1.5 worked just fine with that pool.
There is some more room for improvement, especially on zr5.
With scmorse/ziftr-cpu which is ig0tik3d/ziftr-cpu with stratum,
I get about 640 khash on Core i7-4790K CPU @ 4.40GHz and with your miner I got as close to 600 khash...
Just my 2 cents.

Just my 2 cents.
Thanks for the feedback, I'll look into it.
Edit: No rejects for me with default options at yiimp. I also reviewed the code and found no changes that would affect zr5.
Can you confirm that 3.1.5 & 3.1.6 behave differently? Could you also try yiimp?
When I mine the diff is reported as .013. You could try setting the diff manually. On yaamp clones it is in the password
string ( -p d=n ), but your pool may be different.
Edit2: I took a look at the scmorse implementation and i might be able to do better. His implemetation does not use the
aes-ni optimized groestl. If I can integrate that it should hash even faster.
Merging my optimizations with scmorse gave a 33% increase to zr5 but I'll wait to release it until your issue is understood.
Well after recompile of v3.1.6 on my Ubuntu box there is no low-diff rejects on ziftrpool.io
v3.1.5 is also good, but little bit (about 5 khash) slower.
Guess it was something wrong with the previous compile...
(I think I used ./build.sh script)33% more harshrate on ZR5 sounds just AWESOME!
I expect that my Core i7-4790K will go upto ~800 khash...
Just to compare - an older GPU, AMD HD6870 makes 860-900 khash average with wolf's GPU miner @ 845 MHz...
I haven't looked at build.sh since the fork, I should clean it up. Thanks for the tip about scmorse.
