Hibernate version: 3.0.5
Database: Postgres 8.1

Is there any way to reduce the latency for querying?

I have got a huge number of queries that are generated as simple select statements by hibernate. One select statement needs approx 30ms to return back a result and if I have got 1000 of them then I get a response time of 30000ms (30secs).

If I execute those 1000 select statements with psql or pgAdmin it takes about 50ms to generate a result.

I already tried to use pooled connection using org.apache.commons.dbcp.BasicDataSource but the performance gain is marginal and not notworthy.

Another thing I tried ist to deactive transaction services at all but I got no better results.

What other ways do I have to improve latency performance using Hibernate?

Such latency times using hibernate makes the use of databases useless from my point of view.

I would suggest investigating and eliminating causes for so many queries by converting multiple queries into batches or single selects. For example by adjusting fetch policy from select to join.

as the last resort you could use native SQL
