Bequeath vs. TNS connections

I have been doing some speed comparisons between using the bequeath and TCP methods of connecting to a local 8.1.7 database (SuSE Linux) and found the TCP method faster! This is the opposite of what I would have thought to be the case since BEQ doesn't involve a roundtrip to the network card.

I did my measurements using the tnsping utility and here are the results:

% tnsping rsm_beq 10

...
Attempting to contact
(ADDRESS=(PROTOCOL=BEQ)(PROGRAM=oracle)(ARGV0=oracleRSMi)(ARGS='(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))'))

OK (20 msec)

RSM.icada.net = (DESCRIPTION =

      (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521)))

      (CONNECT_DATA =(SERVICE_NAME = RSM))) RSM_beq.icada.net =

    (DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = BEQ) (PROGRAM = oracle)

     (ARGV0 = oracleRSM) (ARGS =
'(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))')))

     (CONNECT_DATA = (SERVICE_NAME = RSM))) Does anyone know why this is the case?
