Fedora core 3 is slower than Fedora core 1?

in Fedora core 1:
abc=# select version();explain select * from abc;select count(*) from abc;
version
-------------------------------------------------------------------------------------------------------------------------------
PostgreSQL 7.3.4 on i386-redhat-linux-gnu, compiled by GCC i386-redhat-linux-gcc (GCC) 3.3.1 20030903 (Red Hat Linux 3.3.1-3)
(1 row)

Time: 0.35 ms
QUERY PLAN
--------------------------------------------------------
Seq Scan on abc (cost=0.00..20.00 rows=1000 width=16)
(1 row)

Time: 0.52 ms
count
-------
30167
(1 row)

Time: 35.84 ms

in Fedora core 3:
abc=# select version();explain select * from abc;select count(*) from abc;
version
-------------------------------------------------------------------------------------------------------------------------
PostgreSQL 7.4.5 on i386-redhat-linux-gnu, compiled by GCC i386-redhat-linux-gcc (GCC) 3.4.1 20040815 (Red Hat 3.4.1-9)

But the speed of ftp and http is sameness.
