Work fine!
Linux OpenSuse 42.3
The Linux daemon included with the QT version did not seem to work stand-alone (wanted to use CLI again). It seemed to start fine, but did not create the hidden directory as before. I switched back to a saved copy of the 7z and that worked as expected.
Also, I switched to Linux from Windows 10 on a second server (first was already on Linux and doing much better) and got ~50% hash improvement (121kh/s to 183kh/s). I'm assuming due to how Linux assigns cores... using hyperthreaded cores gave very little improvement in hash rate. Is there a way to assign cores in the .conf file for Windows (odd/even vs. linear)?
I experienced a 33% speedup when going from mining in the Windows wallet under Wine to mining with the Linux daemon (original one (6206872 Mar 27 17:56 zettelkastend) that I *may* have compiled myself -- don't remember). The interesting thing about that is that the Linux scheduler was doing the scheduling in both scenarios. And, supposedly Wine doesn't have an emulation layer (Wine Is Not an Emulator, heh) and causes very little degradation in my experience.
So, I don't think the difference is related to the Windows scheduler.
Edit: the daemon included with the new Linux QT wallet appears to be the original one from Mar 27 -- and not one that I compiled.
