The default setting for FB 1.5 SS is to use the first CPU(or virtual
CPU). So, you don't have to configure that setting. When I mean HT and
SMP support for FB 1.5 SS doesn't work properly(performance wise), is
changing the CPUAffinity setting for FB 1.5 SS, so that it uses all
CPUs/virtual CPUs available on the system. When setting the
CPUAffinity to only use one CPU, you shouldn't encounter any
performance problems.

If you don't encounter severe performance problems, then you can keep
it enabled.
