That's an impressive improvement. It doubled my hash power with a small decrease in power consumption. My spidey sense is tingling, there will be a big jump in difficulty soon.
On the old miner I found that I'd get a small increase in hash power by running more threads than cores, for this one there isn't any advantage to extra threads.

Pooler, you are amazing. Thanks for your hard work.
Coblee, hearing that from you is such a huge compliment and honor...
Thank you!

I have added some details for the curious in the original post, check them out.
hey pooler, really great job you have done!
the results for my intel-cpu's are:
~ 100 % more hashing-power
~ 15 % less energy amount (for doubled mining-power!)
now we know, why the intel-cpu's are more expensive
i'll set up the donation at your pool to 30 %, mining with 235 KH/s now

My Xeon E5335's (clovertown) jumped 50% from 1.97 KH/s/thread to 2.97.
My Xeon X3430's jumped 58% from 2.28 to 3.62
Very nice. Props to Pooler!
My Opteron 8218's moved about 5% from 2.54 to 2.68
My Sempron 140's moved about 8% from 2.65 to 2.88
Those are nice improvements too.
BTW - I used CFLAGS="-march=native -O3" I tested with and without the sse extensions and it didn't matter (like Pooler said earlier in this thread).

AMD Athlon 3800+ (2.4Ghz) single core:
old: 1.07Kh/s
new:~1.5Kh/s ~1.65Kh/s
I'm using mining section from litecoin client to start mining and speed is displayed as: 'Speed ~nan Khash/sec'.
Not a big deal as actual hashrate is displayed in debug mode however though you should know.
Thanks for this improved miner

Barely 5% improvement on my AMD laptop but indeed about 40% better on my Intel server. Pretty neat
December 19, 2011, 03:50:28 PM
It could be very well that someone else optimized a miner and kept it to themselves.. but at the same time its great that Pooler took the time to work on the cpu miner and share his code with all of us!
December 19, 2011, 03:44:26 PM
I think that dark pool already used optimized miner.
No conspiracy? Ok. I hope u are 100% right. But who knows...

I heard rumours about so called "dark pool" that (probably) made 51% attack. Now with improved miner we have more chances to survive such kind of attack. That's good news.
Irrelevant. The "dark pool" can use the improved miner as well.Why the hell we have been using unoptimized miners for 2 months?
Laziness? Conspiracy?
Umm, nobody had taken it upon themselves to further optimize the miner? No conspiracy theories here. Laziness? Conspiracy?

Price of LTC fell below the floor. Someone mined and sold a lot of coins...

Thank you for reporting this, I have added the DLL to the package.
In w7x64:Code:
Faulting application name: minerd.exe, version: 0.0.0.0, time stamp: 0x4eef5c94
Faulting module name: pthreadGC2.dll, version: 2.8.0.0, time stamp: 0x4be6d174
Exception code: 0xc0000005
Fault offset: 0x00000000000036a3
Faulting process id: 0xeb8
Faulting application start time: 0x01ccbe78f0cabebe
BTW, this was with updated binaries.
I have asked diki, who prepared the binaries, on IRC. He told me that pthreads-w64 is still experimental (see http://sourceforge.net/apps/trac/mingw-w64/wiki/Compile%20pthreads) so it may not always work. He suggests you might want to try a different version of the library, like this one:
http://code.google.com/p/mingw-w64-dgn/downloads/detail?name=mingw_dgn_basic-w64-bin-x86_64-20110225.7z&can=2&q=pthread

Pooler... you rock.. EXCELLENT work. so much for 'high level languages'.
Is there any chance you can compile a version for us linuxcoin users?

This is the shit. I can only test at work on my work laptop, but my mobile i7 @ 1.6ghz went from .7kh/s per thread to 1.68kh/s per thread. That's around %130 increase. I can't wait to try out my i7 at home (running at 4.8ghz with HT.)
December 19, 2011, 02:19:47 PM
Twice as many hashes per second would by 100% better, not 50% better, no?
December 19, 2011, 02:09:15 PM
POOLER!!! YOU FUCKIN ROCK DUDE! I knew you could do it and I had a feeling assembly miner would freakin own!
Fuckin awesome dude! Thanks a ton!
If anyone is wondering - I updated my service installer w/ the new binaries and both 32bit and 64bit now work properly!
