For what it's worth, on my aging Gentoo Linux workstation with a Pentium 4 @ 3
GHz, 1 GB RAM and a single 400 GB SATA Seagate Barracuda disk, default
Postgres 8.4.2 installation, I get:

leif@balapapa ~ $ pgbench -i -s 5
                                   
...
leif@balapapa ~ $ pgbench -T 120
starting vacuum...end.
transaction type: TPC-B (sort of)
scaling factor: 5
query mode: simple
number of clients: 1

number of transactions actually processed: 29990
tps = 249.694058 (including connections establishing)
tps = 249.700935 (excluding connections establishing)
