postgresql under Windows is slow

Hi,

anybody has an experience how is stable postgresql under Windows system ?
I tried postgresq 7.1 under Cygwin, Windows 98 and was dissapointed
by very bad performance. Are there something I could tune ?
I got 250 sel/sec on simple select from table with 500 rows !
Under Linux I have 2500 sel/sec.

    Regards,
        Oleg
