You're right indeed. Than you, I wasn't aware of that.

Yes of course.

:) Probably true.

I realised that I packaged not the original "cpuminer" but its slightly 
optimised fork: 

	https://github.com/pooler/cpuminer

That's probably why it appears to be faster than cgminer on CPU.
For "cgminer" CPU mining "is no longer under active development".

That's the one I had packaged. :)

Thanks, your hints are always much appreciated. :)

It'll be easier to focus our attention on cgminer only.

Feel free do delete "cpuminer" repository or I'll drop it myself later at 
convenient time.
