this message means that Firefly detected that HTT
(Hyper-Threading Technology) is enabled in your hardware.

Firefly takes this information into account and tries to speedup
some types of jobs (e.g., MCQDPT2, XMCQDPT2, MP3/MP4 etc...)
using additional logical cores.

However, this is indeed the warning message as on some hardware
in combination with certain ACPI BIOSes, Operating Systems,
and system drivers, enabling HTT may have negative impact on
the Firefly's performance.
