Can anyone else reproduce these results? I'm on similar hardware (2.5GHz
P4, 1.5G RAM) and my test results are more like this:

(postgresql 8.2.0)

CFLAGS=(default)

tps = 527.300454 (including connections establishing)
tps = 528.898671 (excluding connections establishing)

tps = 517.874347 (including connections establishing)
tps = 519.404970 (excluding connections establishing)

tps = 534.934905 (including connections establishing)
tps = 536.562150 (excluding connections establishing)

CFLAGS=686

tps = 525.179375 (including connections establishing)
tps = 526.801278 (excluding connections establishing)

tps = 557.821136 (including connections establishing)
tps = 559.602414 (excluding connections establishing)

tps = 532.142941 (including connections establishing)
tps = 533.740209 (excluding connections establishing)


CFLAGS=pentium4

tps = 518.869825 (including connections establishing)
tps = 520.394341 (excluding connections establishing)

tps = 537.759982 (including connections establishing)
tps = 539.402547 (excluding connections establishing)

tps = 538.522198 (including connections establishing)
tps = 540.200458 (excluding connections establishing)
