mnogosearch -- pgsql seem so slow, please help me find out why

pgsql 7.1-current, mnogosearch-3.1.8, netbsd/alpha-1.5.1-current, dec
alpha 500, 1G ram, uw-scsi

i'm trying to find out why postgres is the bottle neck in my searches with
mnogosearch. i've tried both the search.c and php version of search and
they both took up to 50 seconds for a one word search. this is with the
system sitting pretty much idle.

'select * from url' from psql monitor took 59 seconds.

mnwork=# explain select * from url;
NOTICE:  QUERY PLAN:

Seq Scan on url  (cost=0.00..14473.56 rows=99256 width=144)

here is my url table:

mnwork=# \d url

i just can't tolerate this kind of results for searching. any suggestions
to overcome this would be appreciated. tia.
