hm .. just ran your benchmark on my personal webserver box
(fbsd 4.8, t-bird 1000; 512MB ram, two WD800JB w/ 8MB cache
in a vinum raid1 config, softupdates enabled; pgsql 7.3.2,
fsync=true, shared buffers=512, max_connections=250 everything
else default)
: real 7m17.967s
: user 0m0.017s
: sys 0m0.000s
looking at systat output during the benchmark .. it shows
quite some heavy disk-io (peaks w/ 660tps and transfers in excess
of 40MB/s) .. so if your box is falling back to PIO this would
definately be a reason for the lousy results.
regards,
alex.
