Maybe you can performe your database changing some parameters properly:
PostgreSQL configuration:
listen_addresses = '*' # what IP address(es) to listen on;
port = 5432 # (change requires restart)
max_connections = 500 # (change requires restart)
Set it to 100, the highest value supported by PostgreSQL
shared_buffers = 16GB # min 128kB
This value should not be higher than 8GB
temp_buffers = 64MB # min 800kB
work_mem = 512MB # min 64kB
maintenance_work_mem = 30000MB # min 1MB
Given RAM 96GB, you could set it up to 4800MB
checkpoint_segments = 70 # in logfile segments, min 1,
16MB each
effective_cache_size = 50000MB
Given RAM 96GB, you could set it up to 80GB
Hope it can help.
Giuseppe.
