postgres的性能非常慢

Question

Postgres configuration

max_connections = 80
maintenance_work_mem = 1GB
effective_cache_size = 13GB
work_mem = 112MB
wal_buffers = 8MB
shared_buffers = 4GB

Answer 1

@Bhanu , You should work on postgresql.conf . You need to change some settings like max_connections,shared_buffers,effective_cache_size,work_mem,maintenance_work_mem,wal_buffers,default_statistics_target .

Increase the size of these variables in config file as per your hardware configuration.
