I'd do mtune=generic instead, which tunes to the most common cpus, since march=native will produce code that only runs on your cpu.

Oh how I wish I had some Xeons.

Impressive. CPU and pps? edit: Oh i guess 4500 pps. 

Also thx anonppcoin, works great!

No. the sourcecode that you edited must be compiled first. Easy on Linux, bit harder on Windows, which is why it will take a bit until an exe will be made.

@ spoid: No, use listtransactions for that.

Seeing ~1000 pps on 7 cores of an i7 930 and ~200pps on an old Centrino Duo, indeed doubled the primes per second. 

Can someone tell me what this mysterious new command might do?  

Tell me more!

It has to be statically compiled, not sure if the makefile does that already or not, not so compiler savvy.

do the following on your product:
strip primecoind
 

read page 4 

Nice, thx for the Windows exe. A lot faster than the original one on my Core2, at least measured in pps (69 now, 30 before).
Maybe mtune=generic would be better for a "release" client.

Nice guide, and very nice to post the binary tacotime! Too bad I'm on a 32 bit Mint and my server has no graphical UI.
Any chance of you or someone else uploading the three modified source files? I tried doing it myself but compiler ran into trouble, guess i made some mistakes...

It's a daemon, running in the background. This site should help you.

e.g. ./primecoind getinfo

USE_UPNP=- 

Those are the source files, i.e. not compiled.

"confirmations" : 2895,

Sure, do you know someone who could recieve and send Primecoins? I also would be willing to deal in batches of 10 XPM or even smaller if you want.

What a spread. 

Want to sell 100 Primecoins, 0.01 BTC or 0.3 LTC each.

Like there just with primecoin.
