Hello all,
I have a query which takes about 20
minutes to execute and retrieves 2000-odd records. The explain for the
query is pasted here
http://explain.depesz.com/s/52f
The same query, with similar data structures/indexes
and data comes back in 50 seconds in Oracle. We just ported the product
to PostgreSQL and are testing it. Any input on what to look for?
Possible relevant parameters are
shared_buffers = 4GB
temp_buffers = 8MB
work_mem = 96MB
maintenance_work_mem = 1GB
effective_cache_size = 8GB
default_statistics_target = 50
It is a machine with 16 GB RAM.
Regards,
Jayadevan
