-O2 generic build: (generally -O3 gives some errors at end but seems to run fine, I'll go the safe route first).

Did you just use the default flags that are in makefile.unix in the master branch?

Nope, I compiled makefile.release created by bitcoin-qt.pro.

I am a bit confused

can't get it work properly

if I set setgenerate true -1 (this is random and it should use all core/threads)
work like 80pps +-20

with setgenerate true 3 works 300pps

i have 8cpu with 4 cores, which will be the best settings I really tried almost all of it but with no success

thanks

Its a i7 3940xm. Cpu core temps are the same. Seems to drop down to 10% increase gradually and then go back up again. Thanks! Good increase so far with O2 Smiley

Lol, installed fabrizziop's build and mined a block with it inside 20 sec Cheesy

Both fabrizziop and Chemisist will be getting a little tip from me shortly Wink  Thanks for your efforts.

This build is -O3 and march=native, it should work on most CPUs as from what I know gcc 4.6.2 only knows up to amd barcelona/K10.

march=native pretty much ensures that it will not be guaranteed to work on any other processor type than what you compiled it with (right?).  Which processor did you compile this on?

FX 8350, and the native build is working too on a Sempron 145, so that's why I guess it must work on other CPUs too.

i3 3225 at fsb 103 so 3.4 GHz (2 cores 4 threads with hyperthreading). Would you recommend this build or your previous one? BTW you're getting tipped if I push past 700 PPS. Currently at 490-540 PPS on Zalfrin's i5 build.

I just remember reading that the results may differ on different processors when compiled with the -march=native flag on the gcc page

Hmmm working here... seems less stable. Goes from 10% decrease to 35% increase and system is a little laggy. Switching back to O2 win patch for now.

Try the -O2 and -O3 builds at my dropbox folder.  To see which one runs better on your system:
1. delete the debug.log (rm ~/.primecoin/debug.log)
2. start one of the builds.
3. Let it run for > 10 minutes and grep the debug.log file for "primemeter"  (grep primemeter ~/.primecoin/debug.log > primemeter-O3.txt)
4. stop the daemon and repeat 1-3 for the other build. Then you can compare the results of 10 time steps of pps and decide which one works best.

(https://www.dropbox.com/home/primecoin%20compiled%20binaries) (I'm uploading an -O2 build in the next 5 minutes.)

(Thanks @fabrizziop for pointing out the -O2 flag)

lol you forgot to share the dropbox folder. In my case the build I made with the best performance is the -O2 -march=native one, the O3 is worse.
