XMR Stak CPU doesnt seem to be running optimally.

I have 2 systems that I mined intensecoin with on a seperate xmrstak cpu miner.

XMR Stak cpu standalone miner
6700k @ 4.4ghz - 300h/s (+/- 30/s)
Ryzen5 1600 @ 3.8ghz/s - 500h/s (+/- 50h/s)

Multipool Miner
6700k @ 4.4ghz -  159h/s
Ryzen5 1600 @ 3.8ghz/s - 267h/s

For Reference this is the config that XMR Stak generated for me on first run for each cpu:

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" : 2 },
    { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 4 },
    { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 6 },
],

Ryzen 5 1600:

"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" : 1 },
    { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 6 },
    { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 8 },
    { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 10 },
    { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 7 },
],
