Hi all,
I am trying to improve the runtime of a big data warehouse
application. One significant bottleneck found was insert performance,
so I am investigating ways of getting Postgresql to insert data faster.
* use COPY instead of Insert, it is much faster
* bundle all Insert into one transaction
* use a separate disk/spindel for the transaction log
I already changed the following config parameters:
work_mem 512MB
synchronous_commit off
shared_buffers 512mb
commit_delay 100000
autovacuum_naptime 10min
Postgres version is 9.6.3 on Ubuntu 17.04 64 bit, on a i7-4790K with
16GB memory and an Intel 750 SSD. JDBC driver is postgresql-42.1.1.
increase shared_buffers, with 16gb ram i would suggest 8gb
Regards, Andreas
