I agree with Nhomar that you shoud upgrade your postgresql. Upgrade to 9.6, first thing. Check that you are not running an old version of the python psycopg2 module ( iirc, v2.5+ is ok )
If you have a separate machine for the database, ensure that the RTT between the DB and ODOO machines, is less than 0.5 milliseconds. I have quite good experience with a setup on two machines ( one DB, one odoo ), they have an average RTT of 0,150 ms. Simply run a ping from your odoo machine to the DB machine to test this.
Make sure that you postgresql configuration is properly set. The default memory parameters are set for low memory usage, not for high performance.Check these parameters: work_mem - maintenance_work_mem - effective_cache_size - shared_buffers - temp_buffers
If possible, consider to upgrade the CPU. For response times, the single-thread performance is still very important.
SSD or nvme disks are very good for DB performance. I'm not a big fan of RAID controllers.
Check your database indexes:
With 300k products postgres trigram indexes might significantly speed up name searches: https://www.postgresql.org/docs/9.6/static/pgtrgm.html - the drawback of these indexes is that they consume a lot of disk space :/
Depending on the number of users, i would increase the number of workers, and have them use less memory. If you tell me that performance is better outside of office hours, this is something to check !!
Check if you have iowait on your DB server, this will tell you if your disks can't keep up. Check the load average on the odoo server: if it is too low, add more workers.

Hi Maxime, Others have already given excellent replies, but I wanted to note a couple of small changes that can give you big rewards: 1. If you are seeing deterioration over time this says to me that increasing number of records added to db are causing longer search/query times. Try to determine what your longest running queries are and see if adding indexes helps. 2. Look at network traffic. Specifically, does odoo and the db communicate on their own network segment separate from all other traffic? Are the users on the local network or do they work remotely? 3. What does top show? If your mem usage, load averages, cpu %, and io wait times are not showing high loads don't worry about any OS parameters or hardware. Look at Odoo postgres. Ok, that was actually 3 things, but I hope you find them useful. Regards, Mike.
