not seeing improvement

[1a1a11a]

compared to Wolf's CPUminer, on CPU E3 1270 and i7 6700K, both are around 100 and 120 for each, any idea why?

Running Ubuntu 14.04 and Ubuntu 16.04

Do you use the latest release? Habe you use the suggested auto config after the first start? Please ost your config!

[1a1a11a]

yes, I used the one in the master branch, I first tried the suggested config, then I also tried using 4, 6, 8 threads, with low-power-mode off and on, always no prefetch

[psychocrypt]

Please post your config. Please post the output of the miner( run it 20sec). Please post the output up to the beginning.

this is on i7 6700K, "cpu_threads_conf" : [ { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 0 }, { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 1 }, { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 2 }, { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 3 }, { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 0 }, { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 1 }, ],

E3 1270 somehow does not support AES according to log, but Intel says it supports AES

[psychocrypt]

You need to change your config. you are mining with two threads on one core, therefore the bad performance. Also you used to much threads, You have 8 MB Cache, therefore you can only use 4 threads.

"cpu_threads_conf" :
[
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 0 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 1 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 2 },
{ "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 3 },
],

[1a1a11a]

but still, it only gives a hash rate around 150 for i7 6700K

@1a1a11a Did you enable the Large page support?

[1a1a11a]

Yes, I run the command in the config.txt and also change the limits in /etc/security/limits.conf Do I have to reboot?

@1a1a11a By default the miner will give you warnings if you don't have the large pages enabled, but will keep on working anyway. Just look for warnings / lack of them to confirm.

@1a1a11a for both your E3 and i7, this should be ideal. Try it out and if it satifies you, I can explain how this works and consider closing the issue. "cpu_threads_conf" : [ { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 0 }, { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 2 }, { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 4 }, { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 6 }, ],
