Does the InterCheck service is hyperthreading compatible?

Hi,

I monitor presently the system monitor on my MacPro Xeon 4cores with Hyperthreading and when I copy files from one drive to another, I could see the InterCheck operation cpu % load to be in the average of 20-25%. When I click on the cpu graph, I could see all 4core plus the 4 ht logical core. The laters are not used at all with this process. 

This observation lead me to put my question here: Does the InterCheck service is hyperthreading compatible?

thank you!
