Dear Team,
Could you please help me, after changing the below parameters in PostgreSQL configuration file it was not reflecting in OS level and also Database performance is degrading.
What were they before you changed them?
Do you mean that the performance is degrading after the change, or that the performance is degrading as the database grows, and your changes have not helped?
Example: I am using Windows 2008 R2 server .For PostgreSQL I have allocated 24GB RAM out of 32GB.
However after changing the below parameters, In task bar it is showing 2.7GB Utilization even though my utilization is more.
So kindly suggest us, whether it will impact or not in Open source PostgreSQL database
max_connections = 100
shared_buffers = 512MB
effective_cache_size = 24GB
work_mem = 110100kB
maintenance_work_mem = 2GB
checkpoint_segments = 64
checkpoint_completion_target = 0.9
wal_buffers = 16MB
default_statistics_target = 100
None of these seem unreasonable. In order to recommend changes, we would have to know more about your database workload. Or better yet, specific queries which seem too slow.
Cheers,
Jeff
