XMR-Stak VS CPUMiner-opt

[NoloConosco]

I apologize in advance if this is in the wrong thread or already discussed; I could not find the answer.

Im relatively new to mining and compiling miners and hoping someone could guide me a bit. I used to mine coins from Cryptonight family using XMR-STAK. I like XMR-STAK because of its low CPU usage and good Hashrate.

I recently started mining other algos using other miners and have become a fan of YescryptR16. I use CPUMiner-OPT to mine YescryptR16 but it uses 100% CPU power.

I did a comparison of both miners on CryptonightV7 with my i7 for 5 minutes each-

• XMR-STAK= 170H/s at 25% CPU Power
• CPUMiner-OPT= 80H/s at 99-100% CPU Power

I understand that they're different miners, made for different things but how can I make CPUMiner-OPT use less CPU power without sacrificing Hashrate (like XMR-Stak)? Or is there another miner for YescryptR16 that is the XMR-Stak equivalent?

Thank you in advance for your guidance.

I mined XMR for a short time and I preferred XMR-Stak (self-compiled with lowered dev-fee).

If you'd like to compile it on your own and don't know how to do it you could check this video:

It's not the best but it should show everything you need.

Thanks, I appreciate the quick reply and link. I've been looking at videos for compiling both but can never seem to get it working correctly. Will keep trying.

cryptonight needs 2mb l3 cache per thread for best efficiency, and xmr-stak detect cache and sets correct amount of threads
it also support large pages, which increase memory access speed

cpuminer-opt, doesnt support large pages and doesnt autodetect l3, so you need to manually set thread count "-t X" to make it more efficient, but even then it will not reach xmr-stak speeds

best CPU miner for any cryptonight variation is JCE CPU Miner. Give it a try and maybe tweak it extensively for maximum hashrate
