is this explain good or bad???

Hey guys,

I'm not sure if this is good or bad but when I want to have a record count
of a view it takes at least 75 seconds to complete (PII 1.4Ghz 256Mb RAM).
Also when I do a record count of one single table (same table but not
joined) it just takes a long time. Firt I want to make sure that the DB is
setup correctly before I jump to HW issues.


This is my sq_logfile table
explain select count(*) from sq_logfile;
Aggregate  (cost=35988.07..35988.07 rows=1 width=0) ->  Seq Scan on sq_logfile  (cost=0.00..33493.86 rows=997686
width=0)

This is ,y sq_flogfile view based on sq_flogfile
explain select count(*) from sq_flogile;
Aggregate  (cost=128282.68..128282.68 rows=1 width=40) ->  Hash Join  (cost=8.65..125788.46 rows=997686 width=40)
-> Hash Join  (cost=6.49..105832.58 rows=997686 width=36)             ->  Hash Join  (cost=4.75..88371.34 rows=997686
width=32)                  ->  Hash Join  (cost=3.69..68416.56 rows=997686
 
width=28)                         ->  Hash Join  (cost=2.58..50955.94 rows=997686
width=24)                               ->  Seq Scan on sq_logfile sl
(cost=0.00..33493.86 rows=997686 width=20)                               ->  Hash  (cost=2.26..2.26 rows=126 width=4)
                                 ->  Seq Scan on sq_contenttypes ct

           ->  Seq Scan on sq_requestmethods rm
