I am running some simple queries to benchmark
Postgres 8.1 against MS Access and Postgres is 2 to 3 times slower that
Access. Hardware: Dell Optiplex GX280 P4 3.20 GHz 3GB RAM Windows XP SP1 Database has one table with 1.2 million rows Query: UPDATE ntdn SET gha=area/10000 I could post the EXPLAIN ANALYZE results but its
4,000+ lines long I’ve run various tests on a number of Postgres
parameters; none of which have come close to Access’ time of 5.00 min. Postgres
times range between 24 min and 121 min. Some of the Postgres variables and ranges I’ve
tested. work_mem: 1,000 to 2,000,000 temp_buffers: 1,000 to 10,000 shared_buffers: 1,000 to 64,000 sort_mem: 1,024,000 fsync on / off Why does Access run so much faster? How can I
get Postgres to run as fast as Access? Thanks, Jay |
