Can you please suggest what will be the suitable memory settings for Postgresql11 if we have 80gb RAM, 16 CPU’s and OS Linux. If we set 25 % of total RAM then shared_buffers value will be 20GB. Will it be useful or we can set it any random vale like 8g or 12gb.
According to https://pgtune.leopard.in.ua/#/ below are the suggested memory values for 80gb RAM and 16 CPU. I assume the values preferred for effective_cache_size = 60GB and shared_buffers = 20GB are too large. max_connections = 500 shared_buffers = 20GB effective_cache_size = 60GB maintenance_work_mem = 2GB checkpoint_completion_target = 0.7 wal_buffers = 16MB default_statistics_target = 100 random_page_cost = 1.1 effective_io_concurrency = 300 work_mem = 6553kB min_wal_size = 1GB max_wal_size = 2GB max_worker_processes = 16 max_parallel_workers_per_gather = 8 max_parallel_workers = 16 Please give your suggestions.
