Multithread processing in TS 6.7.x on UNIX

System

I am looking for the ability(or lack of) for TS 6.7.x to work in a multithread core environment on UNIX(specifically Solaris). I am evaluating new SUN HW for deployment of TS 6.7.1 and the Sun 'T' series with single UltraSPARC T1 multicore processors that are attractive prospects but can be problimatic for applications that do not support multithread processing. To date, I have found no info on TS 6.7.x multithread capabilities or recommendations for or against TS installations running on these type processors.
Will TS work well on single socket, multicore/multithread processors like the Sun UltraSPARC T1 or will it be dog slow because it requires multisocket multiple processors?
TX for your input.
