VBR Sybase Multi Thread question

Hi All,

I installed VBR 6.6 on a Sun T2000 Server with one 8 cores and 32 threads processor.
After installing VBR I found out that everytime I run any report, the DBSRV10 daemon uses only one thread and all other 31 threads are idle.
This makes the report generation too slow although CPU utilization is less than 5%.

Is this a Sybase limitation?
Is there anyway to change this and make Sybase/VBR work multithreaded?
