Interesting discovery: I've found that on my system I can't use more than about 50% of my cores before I run into some kind of bottleneck when mining Securecoin.
See
https://bt.irlbtc.com/view/216672.msg3089740#msg3089740 but here is what I'm getting:
setgenerate true 1: 36Kh/s, 101% CPU (61% idle)
setgenerate true 2: 69Kh/s, 198% CPU (52% idle)
setgenerate true 3: 98Kh/s, 290% CPU (35% idle)
setgenerate true 4: 115Kh/s, 366% CPU (27% idle)
setgenerate true 5: 90Kh/s, 360% CPU (26% idle)
setgenerate true 6: 68Kh/s, 283% CPU (35% idle)
setgenerate true 7: 47Kh/s, 262% CPU (39% idle)
setgenerate true 8: 46Kh/s, 259% CPU (37% idle)
This is with a dual quad-core 2.8GHz Xeon. I'm hitting a limit of about 120Kh/s, and this seems to be regardless of whether I run multiple instances in virtual machines, use CPUminer, or whatever. I'm curious what the bottleneck might be.
To be clear: by using various schemes (CPUminer, multiple instances in virtual machines) I can get my CPU usage up over 700% (as mentioned before in this thread.) What I can't do is get any more hashes out of it than I can with half my cores running. Any ideas what the bottleneck might be?
