Hi All,
Here are some of the results i got after performing pgbench marking between
postgresql 7.4.5 and postgresql 8.1.2. having parameters with same values in
the postgresql.conf file.
postgres@machine:/newdisk/postgres/data> /usr/local/pgsql7.4.5/bin/pgbench
-c 10 -t 10000 regression
starting vacuum...end.
transaction type: TPC-B (sort of)
scaling factor: 10
number of clients: 10
number of transactions per client: 10000
number of transactions actually processed: 100000/100000
tps = 80.642615 (including connections establishing)
tps = 80.650638 (excluding connections establishing)
postgres@machine:/newdisk/postgres/data> /usr/local/pgsql/bin/pgbench -c 10
-t 10000 regression
starting vacuum...end.
transaction type: TPC-B (sort of)
scaling factor: 10
number of clients: 10
number of transactions per client: 10000
number of transactions actually processed: 100000/100000
tps = 124.134926 (including connections establishing)
tps = 124.148749 (excluding connections establishing)
Conclusion : So please correct me if i am wrong ... this result set shows
that the postgresql version 8.1.2 has perform better than 7.4.5 in the
bench marking process since 8.1.2 was able to complete more transcations per
second successfully .
