How do I adjust max_fsm_pages

Hi,
      My postgresql configuration is

  max_locks_per_transaction = 256
   max_connections = 200
   shared_buffers = 6000
   max_fsm_pages = 200000
   max_fsm_relations = 1500

  My serversers total RAM=32GB

      Still I am not able to insert more than 10million records, its
taking lot of time. It also gives hint to increse max_fsm_pages.
 So Please suggest me how do I adjust above parameters to avoid errors
and to increase postgres speed performance?

Thanks ,
Amar
