HI,
I've looking around the log files of my server and lately they indicate that I should consider increase the check_point segments because they're beeing reading too often and also recommend increasing the max_fsm_pages over 169728...
those are the config values present in the postgresql.conf
shared_buffers = 1000 # min 16 or max_connections*2, 8KB eachwork_mem = 8192 # min 64, size in KBmaintenance_work_mem = 262152 # min 1024, size in KBmax_fsm_pages = 40000 # min max_fsm_relations*16, 6 bytes eachmax_fsm_relations = 2000 # min 100, ~70 bytes each
And the new values, acording to the HNIT in log files ...
shared_buffers = 1000 # min 16 or max_connections*2, 8KB eachwork_mem = 8192 # min 64, size in KBmaintenance_work_mem = 262152 # min 1024, size in KBmax_fsm_pages = 170000 # min max_fsm_relations*16, 6 bytes eachmax_fsm_relations = 10625 # min 100, ~70 bytes each
