</div></div>If you need low latency, you should use sliced threads, as explained<br>
in the documentation.<br>
<br>
Tests show that hyperthreading improves performance by about 25%<br>
overall under normal conditions. Latency is completely unrelated to<br>
performance, except in that if you force low latency settings, you<br>
will hurt performance.<br>

<div>additionally, I'm asking whether using 12 threads instead of 6 on a 4-core i7 improves performance? </div><div><br></div></div>
