Hi there,

I love your miner for YescryptR16 algo. I have some interesting observations.

On my i7-2600, if I use 8 threads I only have like 40h/s per thread. But if I drop down to two I have 90h/s instead per thread

On my miners which mostly feature dual core CPU, I have 100-150h/thread.

I wonder if Hyper-threading hurts the hashrate per thread, or the algorithm doesn't scale well on multi-core CPU. The CPU usage on 8 threads are like 97% on average. SO as the one in dual-core CPU.

Did I miss something I need to optimize, or that's it? I'd love to upgrade my miners to quad-core or even i7 (Sandy bridge CPUs are cheap these days), but I want it to be worth of my investment.

Thanks

That it's because the L3 cache of the processors i think that is the reason why that happens. More threads dont always mean best perfomance.
