Your system has a Haswell cpu and in your Instructions you see AVX2 -> means best use BMI2 compiles!!
If you can't disable HT OFF in Bios (during boot press Delete to enter Bios) is it very normal you see 50% cpu usage..only thing you have to check is if the cpu using both real cores..there exsisting programs to select Processor Affinity to let a program use only these real cores..of course easiest way is to put HT-Off in Bios..
